• Difficulty Level : Easy
• Last Updated : 15 Jun, 2021

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.
• Here we observer a pattern, 8(last number) and 2 ends up in 2nd position, 3rd or 7th on the middle finger, and so on.
• The pattern keeps repeating after every 8 numbers
• 1 to 8
• 9 to 16
• 17 to 24, and so on

Examples:

```Input : 17
Output :1

Input :27
Output :3```
