public int static mirroringIt(String str){ return n; } implement this function so its takes ONE string and remove the characters so it becomes a mirrored word. example: Input: qswwbi Output: 4 remove q s b i "wow" is a mirror word. output : 0 Input : "if" output : 1 remove either I or f because it's two words. don't use 3rd parties library or java.util.
