I got a longer palindrome. The resulting program is quite similar to the original version, but I get to use more modern Python data structures (like a Counter, replacing the bisect class.) See the IPython notebook for more on this version. ...
[LeetCode&Python] Problem 409. Longest Palindrome Given a string which consists of lowercase or uppercase letters, find the length of the longest palindromes that can be built with those letters. This is case sensitive, for example"Aa"is not considered a palindrome here. Note: Assume the leng...
