You only have free questions left (including this one).
But it doesn't have to end here! Sign up for the 7-day coding interview crash course and you'll get a free Interview Cake problem every week.
Write an efficient function that checks whether any permutation of an input string is a palindrome.
You can assume the input string only contains lowercase letters.
"civic" should return True
"ivicc" should return True
"civil" should return False
"livci" should return False
"But 'ivicc' isn't a palindrome!"
If you had this thought, read the question again carefully. We're asking if any permutation of the string is a palindrome. Spend some extra time ensuring you fully understand the question before starting. Jumping in with a flawed understanding of the problem doesn't look good in an interview.
We can do this in time.
