Smallest String consisting of a String S exactly K times as a Substring | KMP algorithm.
Function to return the required string.
Finding the longest proper prefix which is also suffix.
ans string.
Update ans appending the substring K - 1 times.
Append the original string.
Returning min length string which contain exactly k substring of given string.
