Leetcode Daily: 3461. Check If Digits Are Equal in String After Operations I

Usually check out the leetcode daily problem every once in a while.

I do chase the feeling when I solve a hard problem, but the problem this time seems pretty straightforward.

Here is my solution, I think I could make it more optimized with some python built-in functions.

class Solution:
    def hasSameDigits(self, s: str) -> bool:
        while len(s) > 2:
            c = ""
            for i in range(len(s) -1):
                x, y = ord(s[i]) - ord('0'), ord(s[i+1]) - ord('0')
                c += str((x + y) % 10)
            s = c
        return s[0] == s[1
