How do you find the nth character in a string?

Approach:

1. Traverse the string character by character.
2. Check for each character if it matches with the given character.
3. Increment the count by 1, if it matches with the given character.
4. If the count becomes equal to N, return the latest found index.
5. If the count does not match with N after the traversal, return -1.
