Write a function that takes in a string S, a character C1, and another character C2, and switches occurrences of C1 in the first half of string S with occurrences of C2 in the second half of string S. The function should only switch these characters until one of the sides runs out of their respective character. The switching should be done from the outsides of the strings inward; in other words, it should always replace outermost characters first.
