Problem Description

Two students, A and B, from JOI High School took exams in four subjects: Information, Mathematics, Science, and English. Given the scores of these four subjects for both A and B, create a program that outputs the higher total score between A's total score \( S \) and B's total score \( T \). In case of a tie, output \( S \) (which equals \( T \)).

Input Format

The input consists of 2 lines.
The first line contains four integers separated by a single space, representing A's scores in Information, Mathematics, Science, and English, respectively.
The second line contains four integers separated by a single space, representing B's scores in Information, Mathematics, Science, and English, respectively.
Each subject's score is out of 100 points, and no score will be negative.

Output Format

The output consists of a single integer.
