Compare Array Sums

Background

In a programming exercise, you need to compare the sums of elements in two arrays.

Problem Description

Start with two integer arrays, $a$ and $b$, each of length $2$. Consider the sum of the values in each array. Return the array which has the largest sum. In the event of a tie, return array $a$.

Input Format

The input is given from standard input in the following format.

A single line containing four integers $a_1, a_2, b_1, b_2$, representing the two elements of array $a$ and the two elements of array $b$, respectively.

Output Format

Output to standard output in the following format.

Output the array with the larger sum in the format [x, y].

Sample

1 2 3 4

[3, 4]

3 4 1 2

[3, 4]

1 1 1 2

[1, 2]

Sample Explanation

Sample 1: Array $a$ is $[1, 2]$ with sum $1+2=3$. Array $b$ is $[3, 4]$ with sum $3+4=7$. Since $7 > 3$, array $b$ is returned, which is [3, 4].

Sample 2: Array $a$ is $[3, 4]$ with sum $3+4=7$. Array $b$ is $[1, 2]$ with sum $1+2=3$. Since $7 > 3$, array $a$ is returned, which is [3, 4].

Sample 3: Array $a$ is $[1, 1]$ with sum $1+1=2$. Array $b$ is $[1, 2]$ with sum $1+2=3$. Since $3 > 2$, array $b$ is returned, which is [1, 2].
