抄题解不关我事（

不用栈的解法：

#include <bits/stdc++.h>
#define int long long
using namespace std;

signed main() {
	vector<int> a;
	int x;
	while (cin >> x) {
		if (x == 0)
			break;
		a.push_back(x);
	}

	reverse(a.begin(), a.end());

	for (auto &i : a)
		cout << i << " ";

	return 0;
}

#include<iostream>
using namespace std;

int main(){
    int x;
    long long number[100];
    	
    int o=0;
    while(true){
      	cin >> x;
    	if(x == 0) break;
    	else{
    		number[o] = x;
    		o++;
    	}
    }
    	
    for(int i=o-1;i >= 0;i--){
    	cout << number[i] << ' ';
    }
    	
    return 0;
}
