Theory for this problem
+
The core idea of **Modulo Seven of Maximum** is to model the requested operation directly: Given two integers `a` and `b`, compute the larger input, then print the non-negative remainder modulo 7. The reference solution uses `Scanner` for input. Keep only the state needed for this result, choose numeric types that cover the stated bounds, and preserve the exact input/output contract. This makes the solution easier to verify on boundary cases and avoids unrelated work.

['First compute `Math.max(a, b)` and store it as the intermediate result.', 'Then apply `Math.floorMod(result, 7)` to that result and print only the final value.']

import java.util.*;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
long a = sc.nextLong();
long b = sc.nextLong();
long result = Math.max(a, b);
long answer = Math.floorMod(result, 7);
System.out.println(answer);
