function binarySearch(value) { var startIndex = 0, stopIndex = words.length - 1, middle = Math.floor((stopIndex + startIndex) / 2); while (words[middle] != value && startIndex < stopIndex) { // adjust searc...

I have a 2D array, something like the following: [1.11, 23] [2.22, 52] [3.33, 61] ... Where the array is ordered by the first value in each row. I am trying to find a value within the array that is close to the search value - within a certain se...

I'm trying to implement Binary search and everything works fine for all the numbers except the corner cases: const a = [1,2,3,4,5]; function findNum(arr, num) { let start=0, end = arr.length-1, mid = Math.floor((start+end)/2); while(...

Say I have an ordered array with lots of duplicates: var array = [ 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5, ]; I also have code to perform a binary search fo...

This happens to be in JavaScript, but the question applies also to other languages. I have this very long list of words, sorted alphabetically, such as: var myList= [ {word:"abstract", flavor:"old", extraData:...}, {word:&...

Why is my algorithm returning “-1” meaning that target value 73 isn’t in the array? (When clearly 73 is in the array). [this is from Khan Academy, but isn't helping] It's supposed to return either the index of the location in the array...

I've tried binary search in my chrome console. But when I've ran the code, the whole chrome got hanged and I had to kill the pages: var arr = [1, 3, 5, 8]; var binary = function (arr, search) { var low = 0; var high = arr.length - 1...

The following code seems to be unable to find the number in the list. Why might this be? Trying this with the number to search for as '9' and the array of numbers consisting of numbers between 1-10 inclusively. array = [1, 2, 3, 4, 5, 6,...

I'm not sure what the technical term is here so a term I can search would be appreciated. Let's say a character has multiple decisions of different weights. Decision A: 1 Decision B: 3 Decision C: 5 Sum: 9 What the code does is that it a...

I have prepared 2 Javascript functions to find matching integer pairs that add up to a sum and returns a boolean. The first function uses a binary search like that: function find2PairsBySumLog(arr, sum) { for (var i = 0; i < arr.length; i++) {...
