Given a string A consisting of lowercase characters.
We need to tell minimum characters to be appended (insertion at end) to make the string A a palindrome.
1 <= |A| <= 105
A consists only of lower-case characters.
First argument is an string A.
Return a integer denoting the minimum characters to be appended (insertion at end) to make the string A a palindrome.
A = "abede"
A = "aabb"
We can make string palindrome as "abedeba" by adding ba at the end of the string.
We can make string palindrome as "aabbaa" by adding aa at the end of the string.
NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a doubt? Checkout Sample Codes for more details.
