ummm 之前1033完全看不懂題目意思......

本題模擬AC

# include<iostream>
using namespace std;
int a[1000];
bool isok(int N) {
	int n = a[0];
	for (int i = 1; i < N; i++){
		if (a[i] != n)
			return false;
	}
	return true;
}
int main(void) {
	int N;// N個學生
	int tl, tr;
	int c;
	cin >> N;
	while (N) {
		c = 0;//計數多少次
		for (int i = 0; i < N; ++i) {
			cin >> a[i];
		}//錄入資料
		while (1) {
			c++;
			tr = tl = 0;
			for (int i = 0; i < N; ++i) {
				tr = (a[i] /=2);
				a[i] += tl;
				tl = tr;
				if (i&&a[i] & 1)
					a[i] += 1;
			}//拆一半
			a[0] += tl;
			if (a[0] & 1)
				a[0] += 1;
			if (isok(N))
				break;
		}//操作完成
		cout <<c<<" "<<a[0]<<endl;
		cin >> N;
	}
	system("pause");
	return 0;
}
