两个二进制字符串的XOR

给定两个相等长度的二进制字符串A和B ，任务是打印一个字符串，该字符串是二进制字符串A和B的XOR。

例子：

Input: A = “0001”, B = “0010”
Output: 0011

Input: A = “1010”, B = “0101”
Output: 1111

方法：我们的想法是遍历由字符字符串的字符都和如果字符不匹配然后加“1”在回答字符串的字符，否则加“0”的答案字符串生成XOR字符串。

下面是上述方法的实现：

C++

// C++ Implementation to find the 
// XOR of the two Binary Strings
#include
using namespace std;
  
// Function to find the 
// XOR of the two Binary Strings
string xoring(string a, string b, int n){
string ans = "";
      
    // Loop to iterate over the
    // Binary Strings
    for (int i = 0; i < n; i++)
    {
        // If the Character matches
        if (a[i] == b[i])
            ans += "0";
        else
            ans += "1";
    }
    return ans;
}
  
// Driver Code
int main()
{
    string a = "1010";
    string b = "1101";
    int n = a.length();
    string c = xoring(a, b, n);
    cout << c << endl;
}

Java

// Java Implementation to find the 
// XOR of the two Binary Strings
import java.io.*;
  
class GFG {
    // Function to find the 
    // XOR of the two Binary Strings
    static String  xoring(String a, String b, int n){
    String ans = "";
          
        // Loop to iterate over the
        // Binary Strings
        for (int i = 0; i < n; i++)
        {
            // If the Character matches
            if (a.charAt(i) == b.charAt(i))
                ans += "0";
            else
                ans += "1";
        }
        return ans;
    }
      
    // Driver Code
    public static void main (String[] args)
    {
        String a = "1010";
        String b = "1101";
        int n = a.length();
        String c = xoring(a, b, n);
        System.out.println(c);
    }
}
