Create Incremental Azure Storage Accounts on every run - azure-devops

Question

Looking for a script to autogenerate a new storage account
with a prefix dev something like dev01.... and when i rerun the template should increment as dev02.. on second run and so on.
I tried giving the parameters / using default templates in github.
Issue is if i pass on a value under the value the system deploys it fine ,if i give the same name it would rerun and update the existing storage.
Instead i would like it to check if storage account exists and if not create a new account , please advise any pointers if any
Sample Parameters.Json file im using :
"parameters": {
"storageAccountName": {
"value": "dev01"
},

I recommand that you could use the Azure powershell script to customize your logic to do that.
The following is the demo code:
$resourceGroup = "rgName"
$storageAccount = "accountName"
$location = "Central US"
$SkuName = "Standard_LRS"
$kind = "StorageV2"
$i = 0;
while(1)
{
$storage = Get-AzureRmStorageAccount -ResourceGroupName $resourceGroup -Name $storageAccount
if($storage -ne $null)
{
$i++
$storageAccount = $storage.StorageAccountName + $i
$storage = New-AzureRmStorageAccount -ResourceGroupName $resourceGroup -Name $storageAccount -SkuName $SkuName -Location $location -Kind $kind
}
else
{
$storage = New-AzureRmStorageAccount -ResourceGroupName $resourceGroup -Name $storageAccount -SkuName $SkuName -Location $location -Kind $kind
$storageAccount = $storageAccount +$i;
}
if ($storage -ne $null)
{
break;
}
}
