it was about counting the numbers of string pairs that if they are merged we can make a palindrome from the merged string , we can rearrange the alphabet in the merged string in any arbitrary order I think it's a very well known problem I was fascinated by this problem I don't remember it's name

Is one of my favorites, it seems weird at first but after giving it some time and think, it turns into a beautiful adhoc problem. I just love it when seemingly complex problems dissolve into familiar patterns.
