Pseudo codes can be solved with the help of dry run by calculating the output based on the input provided in the question or with the help of random input.

I first wrote the code for the main function by taking all the necessary inputs and calling the calculate function in it.
Then I coded the calculate function for amount of food required.
Below is the code for the same:

#include
using namespace std;
int calculate (int a, int unit, int arr[], int n)
{
if (n == 0)
return -1;
int totalFoodRequired = a * unit;
int foodTillNow = 0;
int house = 0;
for (house = 0; house < n; ++house)
{
foodTillNow += arr[house];
if (foodTillNow >= totalFoodRequired)
{
break;
}
}
if (totalFoodRequired > foodTillNow)
return 0;
return house + 1;
}
int main ()
{
int a;
cin >> a;
int unit;
cin >> unit;
int n;
cin >> n;
int arr[n];
for (int i = 0; i < n; ++i)
{
cin >> arr[i];
}
cout << calculate (a, unit, arr, n);
return 0;
}
