(要cout提示他要輸入嗎?) 然後output是直接cout嗎還是要輸出到檔案? 第一次玩這種題目不清楚希望大神們指教一下謝謝!! 這是題目id 100 我的code如下 #include <iostream> using namespace std; int count_number_of_cycle(int n, int t); int main(){ cout << "輸入 x y" << endl; int x, y; cin >> x >> y; int max = 0; int temp = 0; //find max cycle between x, y for(int i = x; i <= y; i++){ if(max < (temp = count_number_of_cycle(i, 0))) max = temp; } cout << x << " " << y << " " << max << endl; system("pause"); return 0; } int count_number_of_cycle(int n, int count){ if(n == 1) return count + 1; else if(n % 2 == 0) return count_number_of_cycle(n / 2, count + 1); else return count_number_of_cycle(3 * n + 1, count + 1); } 我自己測試都吻合阿他卻說我wrong answer = = 是怎麼回事阿 output格式錯誤嗎? 感謝指教 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 219.70.246.124
