• 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```

Recommended Practice

## C++

 `// CPP Program to Count numbers on fingers``#include ``using` `namespace` `std;` `int` `count_num_finger(``int` `n)``{``    ``int` `r = n % 8;``    ``if` `(r == 0)``        ``return` `2;``    ``if` `(r < 5)``        ``return` `r;``    ``else``        ``return` `10 - r;``}` `// Driver code``int` `main()``{``    ``int` `n;``    ``n = 30;``    ``cout << count_num_finger(n);` `    ``return` `0;``}`

## Java

 `// Java Program to Count numbers on fingers``class` `GFG``{``static` `int` `count_num_finger(``int` `n)``{``    ``int` `r = n % ``8``;``    ``if` `(r == ``0``)``        ``return` `2``;``    ``if` `(r < ``5``)``        ``return` `r;``    ``else``        ``return` `10` `- r;``}` `// Driver Code``public` `static` `void` `main(String[] args)``{``    ``int` `n;``    ``n = ``30``;``    ``System.out.println(count_num_finger(n));``}``}` `// This code is contributed``// by Mukul Singh`

## Python3

 `def` `count_num_finger( n ):``    ``r ``=` `n ``%` `8``    ``if` `r ``=``=` `0``:``        ``return` `2``    ``if` `r < ``5``:``        ``return` `r``    ``else``:``        ``return` `10` `-` `r` `# Driver Code``n ``=` `30``print``(count_num_finger(n))` `# This code is contributed by "Sharad_Bhardwaj".`

## C#

 `// C# Program to Count numbers on fingers``using` `System;``    ` `class` `GFG``{``    ` `static` `int` `count_num_finger(``int` `n)``{``    ``int` `r = n % 8;``    ``if` `(r == 0)``        ``return` `2;``    ``if` `(r < 5)``        ``return` `r;``    ``else``        ``return` `10 - r;``}` `// Driver Code``public` `static` `void` `Main(String[] args)``{``    ``int` `n;``    ``n = 30;``    ``Console.WriteLine(count_num_finger(n));``}``}` `// This code is contributed by Princi Singh`
