vector容器存储的10个坐标拼接成带中括号的字符串坐标

假设每个坐标是一个包含两个整数的pair类型，可以使用以下代码将10个坐标拼接成带中括号的字符串坐标：

#include <iostream>
#include <vector>
#include <sstream>

using namespace std;

int main() {
    vector<pair<int, int>> coordinates = {{1, 2}, {3, 4}, {5, 6}, {7, 8}, {9, 10}, {11, 12}, {13, 14}, {15, 16}, {17, 18}, {19, 20}};
    stringstream ss;
    ss << "[";
    for (int i = 0; i < coordinates.size(); i++) {
        ss << "[" << coordinates[i].first << "," << coordinates[i].second << "]";
        if (i != coordinates.size() - 1) {
            ss << ",";
        }
    }
    ss << "]";
    string str_coordinates = ss.str();
    cout << str_coordinates << endl;
    return 0;
}

输出结果为：

[[1,2],[3,4],[5,6],[7,8],[9,10],[11,12],[13,14],[15,16],[17,18],[19,20]]
