braket rotating
Problem Define a string as a “valid bracket string” if it follows the given rules:
“()”, “[]”, and “{}” are all valid bracket strings. If A is a valid bracket string, then “(A)”, “[A]”, and “{A}” are also valid bracket strings. For example, since “[]” is a valid bracket string, “([])” is also valid.
