Codechef : Problem name " Cost of Groceries " solution in C#

     =============================Problem Statement==========================

==============================Solution in C#=============================

using System;

public class Test

{

public static void Main()

{

    int t=Convert.ToInt32(Console.ReadLine());

for(int i=0;i<t;i++){

    

    string[] array=Console.ReadLine().Split(' ');

    int N=Convert.ToInt32(array[0]);

    int X=Convert.ToInt32(array[1]);

    

    string[] array1=Console.ReadLine().Split(' ');//freshness

    string[] array2=Console.ReadLine().Split(' ');//cost of items

    

    int cost=0;

    for(int k=0; k<N; k++)

    {

       if(Convert.ToInt32(array1[k])>=X){

           cost=cost+Convert.ToInt32(array2[k]);

       } 

    }

    

    Console.WriteLine(cost);

}

}

}

================================Explanation==============================

As for each input of array1 we are checking if the freshness value is equal to or greater than threshold value X as per input
If the above condition is satisfied then for that index K we will fetch value from array2 and add the value to cost variable
Later we will display the cost which is summation of all calculation.
