Write a function called sumZero which accepts a sorted array of integers.

The function should find the first pair where the sum is 0. Return an array that includes both values that sum to zero or undefined if a pair does not exist

 

function sumZero(arr) {
let left = 0;
let right = arr.length -1;
while(left < right) {
	let sum = arr[left] + arr[right];
    if(sum ===0) return [arr[left],arr[right]];
    else if(sum>0) right--;
    else left++;
}
