Your email address will not be published. Therefore, cost = 1 – 0 = 1.Step 2: Change character s to d. Therefore, cost = 1 + 1 = 2 and S = “daad”Hence, the cost is 2. In this case, s2 can be considered a derived string of s, with N * 2 + 1 elements. Problem : Write a program to find whether the string is a palindrome or not.
