Given A string S, you are allowed to convert it to a palindrome by adding characters in front of it. Find and return the shortest palindrome your can find by performing this transformation.
For example:
Given "Aacecaaa", Return "AAACECAAA".
Given "ABCD", Return "DCBABCD".

D. To add a minimum number of characters to a string to become a palindrome.S.The simple approach is to string the longest common subsequence length Len directly against it and its reverse sequence. N-len is the request. (n is the original string length)This is done for the following reasons:Requires a minimum number of characters to be added, we can first find a long palindrome from the original string, and then for the original string does not belon
