Space complexity is wrong -> O(1)

As mentioned in one of the constraints

  • str and pat consist of lowercase English letters

This means when building our hashmap from pat in the worst case it will grow to O(26) . This is a constant number and can be simplified to O(1)

agreed. it can only grow to O(26). I'd also argue that the time complexity is just O(N). We don't really care bout the m since we know that M <= N anyways. It's like we simplify O(2N) to O(N) in this case.
