Check Palindrome and Symmetricity

  1. The given string “S” needs to be a palindrome.
  2. All the characters of the string must be symmetric so that the reflection of the characters remains the same.
  • The symmetric characters are AHIMOTUVWXY.
  • Store the symmetric characters in an unordered set, traverse the string, and if the string contains any non-symmetric character, then return false.
  • If all the characters present in the string are symmetric, then check if the string is a palindrome or not. If the string is a palindrome, then return true, otherwise, return false.
