Given two strings s and t. Find the minimum number of operations that need to be performed on str1 to convert it to str2. The possible operations are:

  1. Insert
  2. Remove
  3. Replace


Example 1:

s = "geek", t = "gesek"
Output: 1
Explanation: One operation is required 
inserting 's' between two 'e's of str1.

Example 2:

Input : 
s = "gfg", t = "gfg"
Explanation: Both strings are same.


Your Task:
You don't need to read or print anything. Your task is to complete the function editDistance() which takes strings s and t as input parameters and returns the minimum number of operation required to make both strings equal. 


Expected Time Complexity: O(n2)
Expected Space Complexity: O(n2)


1 <= Length of both strings <= 100
Both the strings are in lowercase.
