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

Question

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

and here is my code

function ad         


        

Answer 1

You can try to create a new array of length (arr.length-1) inside the function and append the products of adjacent numbers to this new array. Then find the largest number in the array and return it. This will solve the problem with negative product.

function adjacentElementsProduct(inputArray) {
  var arr = inputArray;
  var prodArr[];
  var p;
  for (var i = 0; i < arr.length-1; i++) {
    prodArr[i] = arr[i]*arr[i+1];
  };
  for (j=prodArr.length; j--){
  if (prodArr[j] > p) {
      p = prodArr[j];
    };
  return p;
};

console.log(adjacentElementsProduct([-23, 4, -3, 8, -12]));
