X++ method to calculate Easter Sunday?
static date dateOfEaster(Yr y)
{
int a = y mod 19;
int b = y div 100;
int c = y mod 100;
int d = b div 4;
int e = b mod 4;
int f = (b+8) div 25;
int g = (b-f+1) div 3;
int h = (19*a+b-d-g+15) mod 30;
int i = c div 4;
int k = c mod 4;
int l = (32+2*e+2*i-h-k) mod 7;
int m = (a+11*h+22*l) div 451;
int n = (h+l-7*m+114) div 31;
int p = (h+l-7*m+114) mod 31;
return mkdate(p+1,n,y);
}
I got a little creative so you can enumerate all of the holidays for a given year using GET with a public web service and a little recursion. Play around with this as you like. Just copy/paste to a JOB:
static void HolidayWebService(Args _args)
{
System.Net.WebClient webClient = new System.Net.WebClient();
str holidaysAvailable = "http://www.holidaywebservice.com/HolidayService_v2/HolidayService2.asmx/GetHolidaysAvailable?countryCode=UnitedStates";
str holidayDate = "http://www.holidaywebservice.com/HolidayService_v2/HolidayService2.asmx/GetHolidayDate?countryCode=%1&holidayCode=%2&year=%3";
str retVal = webClient.DownloadString(holidaysAvailable);
XMLDocument doc=XMLDocument::newXml(retVal);
XmlNamedNodemap attributes;
XmlElement root = doc.root();
XmlNode node = root.firstChild();
void getHolidayDate(str _holidayCode, Yr _yr = datetimeutil::year(datetimeutil::utcNow()), str _countryCode = 'UnitedStates')
{
System.Net.WebClient webClientInner = new System.Net.WebClient();
str locRetVal;
;
try
{
locRetVal = webClientInner.DownloadString(strfmt(holidayDate, _countryCode, _holidayCode, _yr));
info(strfmt("[%1] %2", _holidayCode, locRetVal));
}
catch
{
error(strfmt("Error with %1, %2, %3", _holidayCode, _yr, _countryCode));
continue;
}
}
void dig(XmlNode _node, int _depth = 0)
{
XmlNode sib;
;
if (_node == null)
return;
if (_node.hasChildNodes())
dig(_node.firstChild(), (_depth+1));
else
{
if (_node.parentNode().name() == 'CODE')
getHolidayDate(_node.innerText());
}
sib = _node.nextSibling();
if (sib)
dig(sib);
}
;
dig(node);
}

There is a string with random numbers and letters. I need to divide this string into 5 parts. And get List. How to do it? Thanks.
String str = '05b37ffe4973959c4d4f2d5ca0c1435749f8cc66';
Should work:
List<String> list = [
'05b37ffe',
'4973959c',
'4d4f2d5c',
'a0c14357',
'49f8cc66',
];
I know there'a already a working answer but I had already started this so here's a different solution.
String str = '05b37ffe4973959c4d4f2d5ca0c1435749f8cc66';
List<String> list = [];
final divisionIndex = str.length ~/ 5;
for (int i = 0; i < str.length; i++) {
if (i % divisionIndex == 0) {
final tempString = str.substring(i, i + divisionIndex);
list.add(tempString);
}
}
log(list.toString()); // [05b37ffe, 4973959c, 4d4f2d5c, a0c14357, 49f8cc66]
String str = '05b37ffe4973959c4d4f2d5ca0c1435749f8cc66';
int d=1
; try{
d = (str.length/5).toInt();
print(d);
}catch(e){
d=1;
}
List datas=[];
for(int i=0;i<d;i++){
var c=i+1;
try {
datas.add(str.substring(i * d, d*c));
} catch (e) {
print(e);
}
}
print(datas);
}
OR
String str = '05b37ffe4973959c4d4f2d5ca0c1435749f8cc66';
int d = (str.length / 5).toInt();
var data = List.generate(d - 3, (i) => (d * (i + 1)) <= str.length ? str.substring(i * d, d * (i + 1)) : "");
print(data);//[05b37ffe, 4973959c, 4d4f2d5c, a0c14357, 49f8cc66]
If you're into one liners, with dynamic parts.
Make sure to import dart:math for min function.
This is modular, i.e. you can pass whichever number of parts you want (default 5). If you string is 3 char long, and you want 5 parts, then it'll return 3 parts with 1 char in each.
List<String> splitIntoEqualParts(String str, [int parts = 5]) {
int _parts = min(str.length, parts);
int _sublength = (str.length / _parts).ceil();
return Iterable<int>
//Initialize empty list
.generate(_parts)
.toList()
// Apply the access logic
.map((index) => str.substring(_sublength * index, min(_sublength * index + _sublength, str.length)))
.toList();
}
You can then use it such as print(splitIntoEqualParts('05b37ffe4973959c4d4f2d5ca0c1435749f8cc66', 5));
splitWithCount(String string,int splitCount)
{
var array = [];
for(var i =0 ;i<=(string.length-splitCount);i+=splitCount)
{
var start = i;
var temp = string.substring(start,start+splitCount);
array.add(temp);
}
print(array);
}
I try to Encoding the std::string from UTF8,... to Hexadecimal. What I can't do right now is that I can't get the decimal value of each character of the input string to convert it if the input string contains special character which is from the Code Page Identifiers(windows-1258) include Vietnamese character.
At first, I will get the decimal value and then convert it to Binary and then to Hexadecimal. s is my input string. s = "Ồ".
void StringUtils::strToBinary(wstring s, string* result)
{
int n = s.length();
for (int i = 0; i < n; i++)
{
wchar_t c = s[i];
long val = long(c);
std::string bin = "";
while (val > 0)
{
(val % 2) ? bin.push_back('1') :
bin.push_back('0');
val /= 2;
}
reverse(bin.begin(), bin.end());
result->append(convertBinToHex(bin));
}
}
std::string StringUtils::convertBinToHex(std::string temp) {
long long binaryValue = atoll(temp.c_str());
long long dec_value = 0;
int base = 1;
int i = 0;
while (binaryValue) {
long long last_digit = binaryValue % 10;
binaryValue = binaryValue / 10;
dec_value += last_digit * base;
base = base * 2;
}
char hexaDeciNum[10];
while (dec_value != 0)
{
int temp = 0;
temp = dec_value % 16;
if (temp < 10)
{
hexaDeciNum[i] = temp + 48;
i++;
}
else
{
hexaDeciNum[i] = temp + 55;
i++;
}
dec_value = dec_value / 16;
}
std::string str;
for (int j = i - 1; j >= 0; j--) {
str = str + hexaDeciNum[j];
}
return str;
}
If my input only contain "Ồ" this is what my expected output
UTF8 : E1BB92
UTF16 : FEFF 1ED2
UTF16BE : 1ED2
UTF16LE : D21E
This how I do it in Java
Charset charset = Charset.forName(Enum.valueOf(Encoding.class, encodingType).toString());
ByteBuffer buffer = charset.newEncoder().encode(CharBuffer.wrap(inputString.toCharArray()));
byte[] bytes = new byte[buffer.limit()];
buffer.get(bytes, 0, buffer.limit());
result = new ByteField(bytes);
return result;
}
I wrote a program for a binary addition in java. But the result is sometimes not right.
For example if i add 1110+111. The result should be 10101.
But my program throws out 10001.
Maybe one of you find the mistake.
import java.util.Scanner;
public class BinaryAdder {
public static String add(String binary1, String binary2) {
int a = binary1.length()-1;
int b = binary2.length()-1;
int sum = 0;
int carry = 0;
StringBuffer sb = new StringBuffer();
while (a >= 0 || b >= 0) {
int help1 = 0;
int help2 = 0;
if( a >=0){
help1 = binary1.charAt(a) == '0' ? 0 : 1;
a--;
} if( b >=0){
help2 = binary2.charAt(b) == '0' ? 0 : 1;
b--;
}
sum = help1 +help2 +carry;
if(sum >=2){
sb.append("0");
carry = 1;
} else {
sb.append(String.valueOf(sum));
carry = 0;
}
}
if(carry == 1){
sb.append("1");
}
sb.reverse();
String s = sb.toString();
s = s.replaceFirst("^0*", "");
return s;
}
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
System.out.print("First: ");
String input1 = scan.next("(0|1)*");
System.out.print("Second: ");
String input2 = scan.next("(0|1)*");
scan.close();
System.out.println("Result: " + add(input1, input2));
}
}
this function is much simpler :
public static String binaryAdd(String binary1,String binary2){
return Long.toBinaryString(Long.parseLong(binary1,2)+Long.parseLong(binary2,2));
}
you can change Long.parseLong into Integer.parseInt if you don't expect very large numbers, you can also replace parse(Long/Int) with parseUnsigned(Long/Int) since you don't expect your strings to have a minus sign do you ?
You are not considering the case when
help1 + help2 = 3
So your method String add(String binary1, String binary2) should be like this:
public static String add(String binary1, String binary2) {
int a = binary1.length()-1;
int b = binary2.length()-1;
int sum = 0;
int carry = 0;
StringBuffer sb = new StringBuffer();
while (a >= 0 || b >= 0) {
int help1 = 0;
int help2 = 0;
if( a >=0){
help1 = binary1.charAt(a) == '0' ? 0 : 1;
a--;
} if( b >=0){
help2 = binary2.charAt(b) == '0' ? 0 : 1;
b--;
}
sum = help1 +help2 +carry;
if (sum == 3){
sb.append("1");
carry = 1;
}
else if(sum ==2){
sb.append("0");
carry = 1;
} else {
sb.append(String.valueOf(sum));
carry = 0;
}
}
if(carry == 1){
sb.append("1");
}
sb.reverse();
String s = sb.toString();
s = s.replaceFirst("^0*", "");
return s;
}
I hope this could help you!
sum = help1 +help2 +carry;
if(sum >=2){
sb.append("0");
carry = 1;
} else {
sb.append(String.valueOf(sum));
carry = 0;
}
If sum is 2 then append "0" and carry = 1
What about when the sum is 3, append "1" and carry = 1
Will never be 4 or greater
Know I'm a bit late but I've just done a similar task so to anyone in my position, here's how I tackled it...
import java.util.Scanner;
public class Binary_Aids {
public static void main(String args[]) {
System.out.println("Enter the value you want to be converted");
Scanner inp = new Scanner(System.in);
int num = inp.nextInt();
String result = "";
while(num > 0) {
result = result + Math.floorMod(num, 2);
num = Math.round(num/2);
}
String flippedresult = "";
for(int i = 0; i < result.length(); i++) {
flippedresult = result.charAt(i) + flippedresult;
}
System.out.println(flippedresult);
}
}
This took an input and converted to binary. Once here, I used this program to add the numbers then convert back...
import java.util.Scanner;
public class Binary_Aids {
public static void main(String args[]) {
Scanner inp = new Scanner(System.in);
String decimalToBinaryString = new String();
System.out.println("First decimal number to be added");
int num1 = inp.nextInt();
String binary1 = decimalToBinaryString(num1);
System.out.println("Input decimal number 2");
int num2 = inp.nextInt();
String binary2 = decimalToBinaryString(num2);
int patternlength = Math.max[binary1.length[], binary2.length[]];
while(binary1.length() < patternlength) {
binary1 = "0" + binary2;
}
System.out.println(binary1);
System.out.println(binary2);
int carry = 0;
int frequency_of_one;
String result = "";
for(int i = patternlength -i; i >= 0; i--) {
frequency_of_one = carry;
if(binary1.charAt(i) == '1') {
frequency_of_one++;
}
if(binary2.charAt(i) == '1') {
frequency_of_one++;
}
switch(frequency_of_one) {
case 0 ;
carry = 0;
result = "1" + result;
break;
case 1 ;
carry = 0;
result = "1" + result;
break;
case 2;
carry = 1;
result = "0" + result;
breake;
case 3;
carry = 1;
result = "1" + result;
breake;
}
}
if(carry == 1) {
result = "1" + result;
}
System.out.println(result);
}
public static String decimalToBinaryString(int decimal1) {
String result = "";
while(decimal1 > 0) {
result = result + Math.floorMod(decimal1, 2);
decimal = Math.round(decimal1/2);
}
String flipresult = "";
for(int i = 0; i < result.length[]; i++) {
flipresult = result.charAt(i) + flippedresult;
}
return flippedresult;
}
}
I'm creating an app for my semester project. In this project I have a simple class file and a few xaml pages. In one xaml page the code checks the value of a string and depending on that value runs a countdown timer. If the value of string is equal to a certain string then it should call a method from simple class where the value of string is changed and then it should navigate to the next xaml page.
When I call the function the application breaks. No error or anything, it just breaks. I don't know why. I have called other functions of same class file in other xaml files and they work perfect but here I'm having trouble. I guess it has something to do with timer.
xaml.cs:

public partial class Page2 : PhoneApplicationPage

int check;
public Page2()

}
if (global.str == "YOUR LIGHT WILL NOT BE ON FOR UNTIL ATLEAST " + global.x * 15 + " MORE SECS.YOU WILL GET AN UPDATE IN:")
{
check = 2;
}
countDownTimer = new DispatcherTimer();
countDownTimer.Interval = new TimeSpan(0, 0, 0, 1);
countDownTimer.Tick += new EventHandler(countDownTimerEvent);
countDownTimer.Start();
test.Content = "" + "seconds remaining";

I made this code, however this shows a different value for page faults. Please help me.
time is an array which will store the number of times a page is referenced. And "foo" is a function designed to return the minimum time one page in the frame list.
