Minimum operations required to convert all characters of a String to a given Character | Function to find the minimum number of operations required.
Maximum number of characters that can be changed in one operation.
If length of the less than maximum number of characters that can be changed in an operation.
Set the last index as the index for the operation.
Otherwise.
If size of the is equal to the maximum number of characters in an operation.
Find the number of operations required.
Find the starting position.
Print i - th index.
Shift to next index.
Otherwise.
Find the number of operations required.
If n % div exceeds k.
Print i - th index.
Shift to next index.
