Given your tutors constraints, you have two options:

1) Loop through the string character by character and check it.
2) Use a Regex.

Given that simplicity of the task, I would guess that this is very early in your course? If so, go with the first option. Otherwise go with the second, but you will have to learn about regular expressions first.

Solution 2

You have to perform a simple iteration over the character array. It is very basic stuff for a software developer.
