Weak test cases for Stupid Machine Problem Code: STUPMACH

This test case is accepted for two different programs…even the O/P of both programs for a similar test case is different

Both solutions gets AC!!

#include <bits/stdc++.h>
#define int long long
#define MOD 1000000007
#define INF 1000000000000
using namespace std;
signed main()
{
int t;
cin>>t;
while(t–){
int n;
cin>>n;
int arr[n], mn = INT_MAX, count = 0;
for(int i=0; i<n; i++) {
int x;
cin>>x;
mn = min(mn, x);
count+=mn;
}
cout<<count<<endl;
}
return 0;
}

this code gives O/P = 29

#include<bits/stdc++.h>
using namespace std;
#define ll long long
int main(){
ll t;
cin>>t;
while(t–){
ll n;
cin>>n;
ll a[n],mini[n];
for(ll int i=0;i<n;i++)
cin>>a[i];
mini[0]=a[0];
for(ll int i=1;i<n;i++)
{
mini[i]=min(mini[i-1],a[i]);
}
ll ans=0,t=mini[n-1];
ans+=(tn);
for(ll int i=n-1;i>=0;i–)
{
if(mini[i]!=t)
{
ans+=(a[i]-t)
(i+1);
t=mini[i];
}
}
cout<<ans<<endl;
}
return 0;
}

Hello @sahuaman83, welcome to Codechef Community.
Well the first one you shared gives expected output. Anyways, the problem belongs to December Lunchtime 2019 Division B. Here’s the link to the editorial, where you can find the handles of Setter and Tester. This is the invitation to contest in Codeforces blog, where you can find the details of Contest. You can tag respective people here and question them about the test cases.
I don’t think it is possible to modify the test cases now.
