根据题目相邻的反序一下就好了。倒序输出即可。
#include<iostream>
#include<vector>
#include<queue>
#include<cstring>
#include<cmath>
#include<map>
#include<set>
#include<cstdio>
#include<algorithm>
#define debug(a) cout<<#a<<"="<<a<<endl;
using namespace std;
const int maxn=200;
typedef long long LL;
LL a[maxn];
int main(void)
{
cin.tie(0);std::ios::sync_with_stdio(false);
LL t;cin>>t;
while(t--)
{
LL n;cin>>n;
for(LL i=1;i<=n;i++) cin>>a[i];
for(LL i=n;i>=1;i--) cout<<a[i]<<" ";
cout<<endl;
}
return 0;
