Given two positive and distinct numbers, the task is to find the greatest of two given numbers without using any conditional statements(if…) and operators(?: in C/C++/Java).

Examples:

```Input: a = 14, b = 15
Output: 15

Input: a = 1233133, b = 124
Output: 1233133```

The Approach is to return the value on the basis of the below expression:

a * (bool)(a / b) + b * (bool)(b / a)

The expression a / b will give 1 if a > b and 0 if a < b (only after typecasting the result to bool).
Hence, the answer will be of the form either a + 0 or 0 + b depending upon which one is greater.

## C++

 `// C++ program for above implementation``#include ``using` `namespace` `std;` `// Function to find the largest number``int` `largestNum(``int` `a, ``int` `b)``{``    ``return` `a * (``bool``)(a / b) + b * (``bool``)(b / a);``}` `// Drivers code``int` `main()``{``    ``int` `a = 22, b = 1231;``    ``cout << largestNum(a, b);` `    ``return` `0;``}`

## Java

 `// Java program for above implementation``class` `GFG``{` `    ``// Function to find the largest number``    ``static` `int` `largestNum(``int` `a, ``int` `b)``    ``{``        ``return` `a * ((a / b) > ``0` `? ``1` `: ``0``) + b * ((b / a) > ``0` `? ``1` `: ``0``);``    ``}` `    ``// Drivers code``    ``public` `static` `void` `main(String[] args)``    ``{``        ``int` `a = ``22``, b = ``1231``;``        ``System.out.print(largestNum(a, b));``    ``}``}` `// This code is contributed by 29AjayKumar`

## Python3

 `# Function to find the largest number``def` `largestNum(a, b):``    ``return` `a ``*` `(``bool``)(a ``/``/` `b) ``+` `\``           ``b ``*` `(``bool``)(b ``/``/` `a);` `# Driver Code``a ``=` `22``;``b ``=` `1231``;``print``(largestNum(a, b));` `# This code is contributed by Rajput-Ji`

## C#

 `    ` `// C# program for above implementation``using` `System;` `class` `GFG``{` `    ``// Function to find the largest number``    ``static` `int` `largestNum(``int` `a, ``int` `b)``    ``{``        ``return` `a * ((a / b) > 0 ? 1 : 0) + b * ((b / a) > 0 ? 1 : 0);``    ``}` `    ``// Driver code``    ``public` `static` `void` `Main(String[] args)``    ``{``        ``int` `a = 22, b = 1231;``        ``Console.Write(largestNum(a, b));``    ``}``}` `// This code is contributed by Rajput-Ji`
