The task is to Add two number using ‘-‘ operator.
Examples:
Input : 2 3
Output : 5Input : 10 20
Output : 30
The idea is simple, we subtract -b from a.
C++
// CPP program to add two numbers using // - operator. #include <bits/stdc++.h> using namespace std; // function to add two numbers. int add(int a, int b) { return a - (-b); } // Driver code int main() { int a = 2, b = 3; cout << add(a, b) << endl; return 0; } |
Java
// Java program to add // two numbers using // - operator. import java.io.*; class GFG { // function to add two numbers. static int add(int a, int b) { return a - (-b); } // Driver code public static void main (String[] args) { int a = 2, b = 3; System.out.print(add(a, b)); } } // This code is contributed // by chandan_jnu |
Python3
# Python 3 program to add two numbers # using - operator. # Function to add two numbers def add(a, b): return (a - (-b)) # Driver code if __name__ == "__main__" : a = 2 b = 3 print(add(a, b)) # this code is contributed by Naman_Garg |
C#
// C# program to add // two numbers using // - operator. class GFG { // function to add two numbers. static int add(int a, int b) { return a - (-b); } // Driver code static void Main() { int a = 2, b = 3; System.Console.WriteLine(add(a, b)); } } // This code is contributed // by mits |
PHP
<?php // PHP program to add two // numbers using - operator. // function to add two numbers. function add($a, $b) { return $a - (-$b); } // Driver code $a = 2; $b = 3; echo add($a, $b); // This code is contributed by mits ?> |
Javascript
<script> // Javascript program to add two numbers using // - operator. // Function to add two numbers. function add(a, b) { return a - (-b); } // Driver code var a = 2, b = 3; document.write(add(a, b)); // This code is contributed by itsok </script> |
Output:
5
Time complexity: O(1)
Auxiliary Space: O(1), As constant extra space is used.
