Minimize the count of characters to be added or removed to make String repetition of same substring | Function to find the minimum of the three numbers.
Function to find the minimum number operations required to convert string str1 to str2 using the operations.
Stores the results of subproblems.
Fill dp [ ] [ ] in bottom up manner.
If str1 is empty , then insert all characters of string str2.
Minimum operations is j.
If str2 is empty , then remove all characters of string str2.
Minimum operations is i.
If the last characters are same , then ignore last character.
If the last character is different , then find the minimum.
Perform one of the insert , remove and the replace.
Return the minimum number of steps required.
Function to find the minimum number of steps to modify the string such that first half and second half becomes the same.
Stores the minimum number of operations required.
Traverse the given string S.
Find the minimum operations.
Update the ans.
Print the result.
