/*
Task No 1:
Implement a recursive global function stringCompare which compares two character strings
recursively and:
1. returns 0 if the two strings are equal.
2. If the character of the first string at the index, where the first mismatch occurred, is
greater in ASCII value; then it returns 1
3. else it returns -1.
