差不多代码是这样

#include <bits/stdc++.h>

using namespace std;

void generateSpiralMatrix(int n)
{
    vector<vector<int>> matrix(n, vector<int>(n, 0));

    int num = 1;
    int rowStart = 0, rowEnd = n - 1, colStart = 0, colEnd = n - 1;

    while (rowStart <= rowEnd && colStart <= colEnd)
    {
        // 向下填充
        for (int i = rowStart; i <= rowEnd; i++)
        {
            matrix[i][colStart] = num++;
        }
        colStart++;

        // 向右填充
        for (int i = colStart; i <= colEnd; i++)
        {
            matrix[rowEnd][i] = num++;
        }
        rowEnd--;

        // 向上填充
        if (colStart <= colEnd)
        {
            for (int i = rowEnd; i >= rowStart; i--)
            {
                matrix[i][colEnd] = num++;
            }
            colEnd--;
        }

        // 向左填充
        if (rowStart <= rowEnd)
        {
            for (int i = colEnd; i >= colStart; i--)
            {
                matrix[rowStart][i] = num++;
            }
            rowStart++;
        }
    }

    // 输出生成的螺旋矩阵
    for (const auto &row : matrix)
    {
        for (int num : row)
        {
            cout << setw(3) << std::left << num << ' '; // 宽度为3，左对齐
        }
        cout << '\n';
    }
}

int main()
{
    int n;
    cin >> n;
    generateSpiralMatrix(n);
    return 0;
}

不贴代码,没必要发题解
