Solution: 

1st Method:

#include <stdio.h>

int main(void) {
int t, i, n, a, b, c, d, s;
scanf("%d", &t);
for(i=0;i<t;i++)
{
    if(t>=1 && t<=1000)
    {
        scanf("%d",&n);
        scanf("%d %d %d %d", &a, &b, &c, &d);
        s = a+b+c+d;
        if( s == n && n>=a && n>=b && n>=c && n>=d )
        {
            if(a>=b && a>=c && a>=d)
            {
                printf("%d\n", a);
            }
            else if(b>=a && b>=c && b>=d)
            {
                printf("%d\n", b);
            }
            else if(c>=a && c>=b && c>=d)
            {
                printf("%d\n", c);
            }
            else
            {
                printf("%d\n", d);
            }
        }
    }
}
return 0;
}

2nd Method:

#include <stdio.h>

int main(void)
{
    int t, n, i, j, f, s, a[4];
    scanf("%d", &t);
    for(j=0;j<t;j++)
    {
        scanf("%d", &n);
        for(i=0;i<4;i++)
        {
            scanf("%d", &a[i]);
        }
        s = a[0] + a[1] + a[2] + a[3];
        if( s == n && a[0] <= n && a[1] <= n && a[2] <= n && a[3] <= n)
        {
            //finding the greatest
            for(i=0;i<3;i++)
            {
                //swapping if greater
                if(a[i] > a[i+1])
                    {
                        f = a[i];
                        a[i] = a[i+1];
                        a[i+1] = f;
                    }
                else
                    continue;
            }
            printf("%d\n", a[3]);
        }
        
    }
    return 0;
    
}
