![]() We just have to learn how to give directions in a way that the computer. Therefore, we can solve this by counting the number of occurrences of each character with a dictionary.Įach there is at most 1 character that appears an odd number of times, then that means the string can be rearranged as a palindrome. 5 Coding Coding a computer is like giving someone directions to get through a maze. ![]() That means that either every character has a matching pair, or there is one character that appears an odd number of times (and that character must be placed in the middle of the string). In other words, a palindrome is a string that can be reversed to produce the same string. ![]() Have an odd number of characters, where there’s only one character that appears an odd number of times You should write a couple of palindromes down and see if you can notice any patterns. In order to solve this, we need to think about the properties of a palindrome. Output - True (the letters can be rearranged to “racecar”) Write a function that checks if the letters in the string can be rearranged to form a palindrome ( or if the input is already a palindrome). ![]() As a refresher, here’s the previous question ![]()
