  All text in bold corresponds to input and the rest corresponds to output.

• CODING ARENA

• #include <stdio.h>

  int main()

  {

    int arr[100];

    int n,i,sum=0;

    scanf("%d",&n);

    for(i=0;i<n;i++)

    {

      scanf("%d",&arr[i]);

    }

    for(i=0;i<n;i++)

    {

      sum=sum+arr[i];

    }
