# Program to Count numbers on fingers

Count the given numbers on your fingers and find the correct finger on which the number ends.

- The first number starts from the thumb, second on the index finger, third on the middle finger, fourth on the ring finger and fifth on the little finger.
- Again six comes on the ring finger and so on.

**Examples:**

Input : 17 Output :1 Input :27 Output :3
