在c++示例代码中将矩阵向左旋转90度

int matrix[3][3] = {
    {1, 2, 3},
    {4, 5, 6},
    {7, 8, 9}
};

int rotatedMatrix[3][3];

for (int i = 0; i < 3; i++) {
    for (int j = 0; j < 3; j++) {
        rotatedMatrix[j][2 - i] = matrix[i][j];
    }
}

for (int i = 0; i < 3; i++) {
    for (int j = 0; j < 3; j++) {
        cout << rotatedMatrix[i][j] << " ";
    }
    cout << endl;
}

#include <iostream>
using namespace std;

int main() {
    int matrix[3][3] = {
        {1, 2, 3},
        {4, 5, 6},
        {7, 8, 9}
    };

    int rotatedMatrix[3][3];

    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            rotatedMatrix[j][2 - i] = matrix[i][j];
        }
    }

    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            cout << rotatedMatrix[i][j] << " ";
        }
        cout << endl;
    }

    return 0;
}
