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 are initializing the variable p to zero. That means any multiplication values smaller than that are not accepted. Rather set it to the smallest possible integer value:

var p = Number.MIN_SAFE_INTEGER;

function adjacentElementsProduct(inputArray) {
  var arr = inputArray;
  var x = 0;
  var y = 0;
  var p = Number.MIN_SAFE_INTEGER;
  for (var i = 0; i < arr.length; i++) {
    x = arr[i];
    y = arr[i + 1];
    if (x * y > p) {
      p = x * y;
    };
  };
  return p;
};

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