Complexity

• Time: O(N)
• Space: O(1)

2. Please don't edit the function prototype provided in question.c, your . solution might not compile if you do.
3. If you need hints to solve the problem, look at hints.c instead.
4. When you're done, compile your changes by running: make all
5. Test your code using: ./question < input.txt or ./hints < input.txt.
