A string S is given on one line from standard input. If S is a palindrome (reads the same forwards and backwards), output Yes; otherwise, output No, on one line.
For example, level is a palindrome, so the answer is Yes, while hello is not, so the answer is No.
Constraints
1 ≤ length of S ≤ 100 (S consists only of lowercase letters)

How to ask the AI
Tell the AI whether to distinguish between uppercase and lowercase letters, and how to judge the result for an empty string or a single character. It's also important to keep the output wording consistent, such as Yes/No exactly as specified.
If you ask vaguelyIf a string with mixed uppercase and lowercase letters is passed, the AI might make its own decision about case sensitivity without it being specified.
