Forward this email to a friend or colleague and challenge them to solve it.

Hi, 

A palindrome string reads the same backward as well as forward. Given a string, write a function to find the minimum number of characters that need to be inserted in order to convert the string to a palindrome.

Below are some examples:

  • aabaa: 0, it's already a palindrome
  • abcd: 3, dcbabcd
  • abcde: 4, edcbabcde

Solution will be written in Python for premium users.
