Given two integer numbers, whenever the bits of the first number is set i.e. 1, toggle the bits of the second number leaving the rest bits of the second number unchanged.
Examples :
Input: 2 5 Output: 7 2 is represented as 10 in binary and 5 is represented as 101. Hence toggling the 2nd bit of 5 from right, thus the new number becomes 7 i.e. 111 Input: 1 3 Output: 2
Approach:
Just do XOR of the given two Number.
C++
// A CPP program toggle bits of n2 // that are at same position as set // bits of n1.#include <bits/stdc++.h>using namespace std;// function for the Nega_bitint toggleBits(int n1, int n2){ return n1 ^ n2;}// Driver program to test aboveint main(){ int n1 = 2, n2 = 5; cout << toggleBitst(n1, n2) << endl; return 0;} |
Java
// A Java program toggle bits of n2 // that are at same position as set // bits of n1.import java.io.*;class GFG { // function for the Nega_bit static int toggleBits(int n1, int n2) { return (n1 ^ n2); } // Driver program public static void main(String args[]) { int n1 = 2, n2 = 5; System.out.println(toggleBits(n1, n2)); }}// This code is contributed// by Nikita Tiwari. |

Output :
7
Time Complexity : O(1)
Auxiliary Space: O(1)
