a good pairs is two adjacent integers whose sum is even. which of the following arrangements of arr[n' code example

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

function adjacentElementsProduct(inputArray) {
    var cb = Number.NEGATIVE_INFINITY;
    for(var i=0;i<inputArray.length-1;i++){
        if(inputArray[i]*inputArray[i+1] > cb){
          cb = inputArray[i]*inputArray[i+1];
        }
    }
  return cb;
}
