一道原创OI题（普及-）——ZCS的随机游走的数据生成器

Code：

#include <iostream>
#include <vector>
#include <string>
#include <cstdlib>
#include <ctime>

using namespace std;

// 生成随机整数
int randInt(int min, int max) {
    return min + rand() % (max - min + 1);

// 生成网格
vector<string> generateGrid(int n, int m, int& start_i, int& start_j) {
    vector<string> grid(n, string(m, '.'));
    // 随机生成初始位置
    start_i = randInt(0, n - 1);
    start_j = randInt(0, m - 1);
    grid[start_i][start_j] = '#';
    // 随机生成障碍物
    for (int i = 0; i < n; ++i) {

            if (i == start_i && j == start_j) continue;
            if (randInt(0, 1) == 1) {

            }
        }
    }

// 生成移动方向

    for (int i = 0; i < x; ++i) {
        opts[i] = randInt(1, 4);
    }
    return opts;
}

// 输出数据到控制台
void outputData(int n, int m, int x, const vector<string>& grid, const vector<int>& opts) {
    // 输出 n, m, x
    cout << n << " " << m << " " << x << endl;
    // 输出网格

    // 输出移动方向
    for (size_t i = 0; i < opts.size(); ++i) {
        cout << opts[i] << endl;
    }
    // 输出分隔符
    cout << "----------------------" << endl;
}

// 生成小数据

        vector<int> opts = generateOpts(x);
        outputData(n, m, x, grid, opts);
    }
}

// 生成大数据
void generateLargeData() {
    for (int i = 1; i <= 10; ++i) {
        int n = randInt(10000, 100000);
        int m = randInt(10000, 100000);

    }
}

int main() {
    srand(static_cast<unsigned int>(time(0))); // 初始化随机数种子
    generateSmallData(); // 生成小数据
    generateLargeData(); // 生成大数据
    return 0;
