The outer loop runs for O(N-1) where N is the length of your input string and the inner loop runs for O(13). So the total runtime is O(N-1 * 13) => O(13N-13) => O(N). Therefore, I think the time complexity would be Linear time.

Since you are using a temporary buffer, charArray, to modify and keep track of the changes, I think that the space complexity would be O(N) also.
