二、參考代碼

#include<iostream>
#include<vector>
#include<cstdlib> 
using namespace std;void generateSchedule(vector< vector<int> >& table, int numPlayers, int rounds) {// 生成比賽日程的函數for (int i = 1; i <= numPlayers; i++) {table[1][i] = i; // 初始化第一輪的比賽對陣}int matchGroupSize = 1;for (int round = 1; round <= rounds; round++) {numPlayers /= 2;for (int group = 1; group <= numPlayers; group++) {for (int i = 1 + matchGroupSize; i <= 2 * matchGroupSize; i++) {for (int j = 1 + matchGroupSize; j <= 2 * matchGroupSize; j++) {table[i][j + (group - 1) * matchGroupSize * 2] = table[i - matchGroupSize][j + (group - 1) * matchGroupSize * 2 - matchGroupSize];table[i][j + (group - 1) * matchGroupSize * 2 - matchGroupSize] = table[i - matchGroupSize][j + (group - 1) * matchGroupSize * 2];}}}matchGroupSize *= 2;}
} int calculateRounds(int numPlayers, int rounds) {// 計算比賽輪次的函數do {numPlayers = numPlayers / 2;rounds++;} while (numPlayers > 1);return rounds;
}void printSchedule(vector< vector<int> >& table, int numPlayers) {// 打印比賽日程表的函數for (int i = 1; i <= numPlayers; i++) {for (int j = 2; j <= numPlayers; j++) {cout << table[i][j] << " ";}cout << endl;}
}int main() {int rounds = 0;int numPlayers = 0;cin >> numPlayers;vector< vector<int> > v(numPlayers + 1, vector<int>(numPlayers + 1)); // 創建比賽日程表的二維數組rounds = calculateRounds(numPlayers, rounds);  // 計算比賽輪次generateSchedule(v, numPlayers, rounds); // 生成比賽日程表printSchedule(v, numPlayers); // 打印比賽日程表return 0;
}
