给定数字K的每个数组元素的XOR

给定一个数组arr和一个数字K ，找到一个新数组，该数组是通过对给定数组K中给定数组执行相应元素的XOR运算而形成的。
例子：

Input: arr[] = { 2, 4, 1, 3, 5 }, K = 5 
Output: 7 1 4 6 0 
Explanation: 
2 XOR 5 = 7 
4 XOR 5 = 1 
1 XOR 5 = 4 
3 XOR 5 = 6 
5 XOR 5 = 0 
Input: arr[] = { 4, 75, 45, 42 }, K = 2 
Output: 6 73 47 40 
 

方法：

1. 遍历给定的数组。
2. 然后，计算每个元素与K的XOR。
3. 然后将其存储为输出数组中该索引处的元素。
4. 打印更新的数组。

下面是上述方法的实现。

CPP

// C++ program to find XOR of every element
// of an array with a given number K
 
#include 
using namespace std;
 
// Function to construct new array
void constructXORArray(int A[], int n, int K)
{
    int B[n];
 
    // Traverse the array and
    // compute XOR with K
    for (int i = 0; i < n; i++)
        B[i] = A[i] ^ K;
 
    // Print new array
    for (int i = 0; i < n; i++)
        cout << B[i] << " ";
    cout << endl;
}
 
// Driver code
int main()
{
    int A[] = { 2, 4, 1, 3, 5 };
    int K = 5;
    int n = sizeof(A) / sizeof(A[0]);
    constructXORArray(A, n, K);
 
    int B[] = { 4, 75, 45, 42 };
    K = 2;
    n = sizeof(B) / sizeof(B[0]);
    constructXORArray(B, n, K);
 
    return 0;
}
