output : leet(t(c)o)de
public String minRemoveToMakeValid(String s){
StringBuilder sb =new StringBuilder();
in open =0;
for (char c : s.toCharArray()){
if(c == '('){
open++
}
else if(c == ')'){
if(open == 0) continue;

Answer 1

import util.control.Breaks._
val searchMe = "peter piper picked a peck of pickled peppers"
var numPs = 0
for (i <- 0 until searchMe.length) {
breakable {
if (searchMe.charAt(i) != 'p') {
break // break out of the 'breakable', continue the outside loop
} else {
numPs += 1
}
}
}
println("Found " + numPs + " p's in the string.")

Im able to get it worked using below code
def minRemoveToMakeValid(s: String): String = {
var open = 0
val sb = new StringBuilder
for (c <- s.toCharArray) {
breakable {
if (c == '(') open += 1
else if (c == ')') {
if (open == 0)break
open -= 1
}
sb.append(c)
}
}
var result = new StringBuilder()
for(i<-sb.length()-1 to 0 by -1)
{
breakable{
open-=1
if(sb.charAt(i) == '(' && open >0) break
result.append(sb.charAt(i))
}
}
result.reverse.toString()
}
