Given an array of integers, find the pair of adjacent elements that has the largest product and return that product JavaScript
We are required to write a JavaScript function that takes in an array of Numbers (positive and negative numbers).
The function should return the highest product of two adjacent elements of the array.
For example −
If the input array is −
const arr = [-23, 4, -3, 8, -12];
Then the output should be −
const output = -12;
and the two elements are 4 and -3
Example
const arr = [-23, 4, -3, 8, -12];
const adjacentProduct = (arr = []) => {
let first = 0;
let second = 0;
let res = Number.MIN_SAFE_INTEGER;
for (let i = 0;
i < arr.length; i++) {
first = arr[i];
second = arr[i + 1];
if (first * second > res) {
res = first * second;
};
};
return res;
};
console.log(adjacentProduct(arr));Output
This will produce the following output −
-12
