You should add "screencast" to the title so that it differs from the announcement title.
Thank you!

I guess there is some issue in judgement of question B
Below are the two solutions , both are accepted
but both are giving diffrent answers on this test case
n = 4
arr = [4 , 8 , 20 , 10] answer should be yes
this is the first solution( giving YES for the above test case)
include<bits/stdc++.h>
using namespace std;
int main() { int tt; cin >> tt; for(int t = 0; t < tt; t++ ) { int n; cin >> n; int a[n]; set s; for(int i=0; i<n; i++) { cin>>a[i]; s.insert(a[i]); } sort(a,a+n);
}
Below is the second one (giving NO for the above test case)
include<bits/stdc++.h>
using namespace std;
int main() { int tt; cin >> tt; for(int t = 0; t < tt; t++ ) { int n; cin >> n; int a[n]; sets; for(int i=0; i<n; i++) { cin>>a[i]; s.insert(a[i]); } sort(a,a+n);
}
why both are accepting
Please send both solutions to the problem and hack one of them using the corresponding interface.
