| 1 | for: 2 122
2 is the number distortions allowed. And, 122 can be turned into palindrome with only 1 distortion, So, it can be accepted as a palindrome.

| 2 | Normally in palindrome the first char is the same as the last char. If a distortion is allowed, they may be different if the number of different chars are less than the allowed distortion number
