Hello I need some help regarding 1553B - Reverse String. At the third testcase in the given input output scenario, the string s is aab and string t is baaa.

If I put the chip at index 2 (on 'b') in string s and move it left twice and then once right, I can obtain the string t. Here is the process.

Put chip at index 2-> A A B

Move left -> A A B

Move left again -> A A B

Now move right -> A A B

This finally gives us BAAA. Unless I am missing something the output should be YES instead of NO. Can anyone help me sort this out? Thanks.
