I am trying to write a function which takes as input an array of strings with only lower case letters. Function returns an array of same strings but with each string has its letter rearranged such that it becomes a palindrome if possible, and if not then it returns -1.
This function works fine for case when input array is like this
- makingworldcode September 13, 2015{"a", "b", "a"}
{"a","b","c"} and so on.
but when i am having input like below:
{"aba", "bb", "cac"} and like this that is array of strings it fails.
Any guidance or suggestion on this is helpful.
