2020 Updated Angry Professor Hackerrank Solution in C++

      Coding Demons presents you the solution for a HackerRank problem "Angry Professor". The solution is given in two stages 

Stage 1: Logic 

Stage 2 : C++ Code

Logic : 

• Take no of test case
• Repeat until all test cases are done
• Take no of students & threshold value
• Before time or on time present students have Negative no or zero
• Late students have positive no
• Count the no of negatives & zeroes (i.e. students on time)
• Compare with threshold
• If less print YES else NO.

Code :

/*** SOLUTION BY CODING DEMONS ***/

#include<bits/stdc++.h>

using namespace std;

int main()

{    

    int t,i;

    cin>>t;

    

    for(i=0;i<t;i++)

    {   

        int n,k,j,x=0;

        cin>>n>>k;

        

        int a[n];

        

        for(j=0;j<n;j++)

        {   

            cin>>a[j];

            if(a[j]<=0)

            {

             x++;

            }

        }

        if(x>=k)

        {     

            cout<<"NO\n";

        }

        else

        {     

            cout<<"YES\n";

        }        

    }

  return 0;

}
