🎆문제

Given an array of integers, find the pair of adjacent elements that has the largest product and return that product.

Example

For inputArray = [3, 6, -2, -5, 7, 3], the output should be
adjacentElementsProduct(inputArray) = 21.

7 and 3 produce the largest product.

function adjacentElementsProduct(inputArray) {
    let result = [];
    for(i = 0; i < inputArray.length-1; i++) {
        result.push((inputArray[i]*inputArray[i+1]))
    }
    return Math.max(...result)
}
