```c++
#include<bits/stdc++.h>
using namespace std;
int s[105];
int main()
{
int t;
int x,y,a,b;
cin>>t;
while(t--)
{
int n;
cin>>n;
int maxx=-1;
for(int i=1;i<=n;i++)
{
cin>>x>>y>>a>>b;
s[i]=abs(a-x)+abs(b-y);
maxx=max(maxx,s[i]);
}
cout<<maxx<<endl;
}
}

Answer 1

public class Test {
    public static void main(String [] args){
        Scanner sc = new Scanner((System.in));
        int x,y,a,b;
        int t = sc.nextInt();
        for (int i = 0; i < t; i++) {
            int n = sc.nextInt();
            int s[] = new int[n+1];
            int maxx = -1;
            for (int j = 1; j <= n; j++) {
                x=sc.nextInt();
                y=sc.nextInt();
                a=sc.nextInt();
                b=sc.nextInt();
                s[j] = abs(a-x)+abs(b-y);
                maxx = max(maxx,s[j]);
            }
            System.out.println(maxx);
        }
    }
}
