对于数字的每个设置位，其他的切换位

给定两个整数，每当第一个数字的位设置为1时，切换第二个数字的位，使第二个数字的其余位保持不变。

例子 ：

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

方法：
只需对给定的两个数字进行异或。

C++

// A CPP program toggle bits of n2
// that are at same position as set
// bits of n1.
#include 
using namespace std;
 
// function for the Nega_bit
int toggleBits(int n1, int n2)
{
    return n1 ^ n2;
}
 
// Driver program to test above
int 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));
    }
}
