Why my program is producing wrong answers in test case 4. plzz hlp

def area(x):
    return x*2 - 4


b = int(input())
for i in range(b):
    c = float(input())
    print(f'Case {i + 1}: {area(c)}')
3

here c would be an integer number. Not a float type number.

How did you get the formula 2x-4?

here total area=nn…
the area of 4 triangle=4{(n-2)n/21/2}
=nn-2n
the area of small square=4(1)
=4
now-the required area=(nn) -{(nn-2n)+4}
=2n-4(ans)

I use the formula ,but it give error in case 3;
my code:
#include<stdio.h>
int main()
{
int t,i;
scanf(“%d”,&t);
int a[t];
for(i=0;i<t;i++)
scanf(“%d”,&a[i]);
for(i=0;i<t;i++)
{
int n;
n=a[i];

    printf("Case %d: %d\n",i+1,n*2-4);
}

}
What’s the problem?

There is some kind of problem since it says right answers as wrong answers.
