There was a problem called little elephant and candies and here are the link and code I wrote respectively :

Link:

My code:

#include <iostream>
using namespace std;

int main() 
{
    int number;
    cin>>number;
    int elephants,candies,total_happy;
    
    for(int i=0;(i<number)&&(number<=1000);i++)
    {
        total_happy=0;
        
        int happy[elephants];
        
        cin>>elephants>>candies;/// First line of input
        
        for(int i=0;i<elephants;i++) /// Second line second line of input
        {
            cin>>happy[i];
            total_happy+=happy[i];
        }
        
        if(total_happy>candies){
            cout<<"No"<<endl;
        }
        else{
            cout<<"Yes"<<endl;

        }
 
    }

}

I honestly feel my logic is right because it works for all the test cases. I don’t understand why it says wrong when I submit it.
It sometimes even says Runtime error when i run the code but when I refresh and run it again, it gives correct output

You declare an array of size elephants before you know what the value of elephants should be. Surprised there is no compiler warning for this.

I changed that part of the code but it still says wrong answer :frowning:

  cin>>elephants>>candies;/// First line of input
        
  int happy[elephants];

Consider the test input:

1
100 1
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

In that case total_happy will be equal to 100, candies will be equal to 1
since total_happy>candies it SHOULD output “No” -

I know :slight_smile: Your most recent submission outputs Yes.
