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(...

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...

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 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++) {...

I have implemented Binary Search Algorithm using Node.js. I am recording the time taken by the algorithm to search for a number in a random generated array. I am able to output the time taken by the algorithm for an unsuccessful search. But I am not...

I'm trying to find a number between min and max. I only know (through using the more method) whether the number I'm guessing is higher or lower than the number passed. The number that I need to find can be a decimal, which is what is making m...

I'm almost embarrassed to ask this question but for whatever reason I cannot get this to work. It's a Khan Academy exercise on binary searches. https://www.khanacademy.org/computing/computer-science/algorithms/binary-searc...

I've written out a recursive method for finding a single item in an array which is not repeated (whereas all other items are in pairs and next to one another). My question is, can this be done without recursion (perhaps with a while loop) and is...
