I'm trying to solve this problem: http://www.hackerrank.com/challenges/mark-and-toys

Mark and Jane are very happy after having their first child. Their son loves toys, so Mark wants to buy some. There are a number of different toys lying in front of him, tagged with their prices. Mark has only a certain amount to spend, and he wants to maximize the number of toys he buys with this money.

Given a list of prices and an amount to spend, what is the maximum number of toys Mark can buy? For example, if and Mark has to spend, he can buy items for , or for units of currency. He would choose the first group of items.

My solution normally works but apparently is incorrect when a very large set of numbers are thrown at it.

// Complete the maximumToys function below. function maximumToys(prices, k) { const pricesSorted = prices.sort(); // console.log('pricesSorted ', pricesSorted); let budget = k; let noToys = 0; pricesSorted.forEach(toyPrice=>{ if (toyPrice <= budget) { noToys++; budget = budget - toyPrice; } }); // console.log('noToys ', noToys); return noToys; }

If you don't pass comparable function to `sort()`

, it assumes the values as strings and sorts them according to Unicode code points. Source: - Sort

So, pass a comaparable function and JS will sort objects depending upon return value of this function. Rest of your code is correct.

const pricesSorted = prices.sort(function(a,b){return a-b;});

**UPDATE:**

Since the `sort()`

sorts in-place, `pricesSorted`

is redundant.

**Mark and Toys,** It should return an integer representing the maximum number of toys Mark can purchase. maximumToys has the following parameter(s):. prices: an array of There are a number of different toys lying in front of him, tagged with their prices. Mark has only a certain amount to spend, and he wants to maximize the number of toys he buys with this money.

Sort the toys according to price and keep taking toys as long as you have money left.

// Complete the maximumToys function below. function maximumToys(prices, k) { var bought = 0 var pricings = prices.sort((a, b) => a - b) var amtLeft = k; for (var i = 0; i < pricings.length; i++){ if (amtLeft < pricings[i]) { break; } else { amtLeft = amtLeft - pricings[i]; bought++; } } return bought }

If you reach a point where he can't afford the cheapest toy in a pass, then he won't be able to afford any of the remaining and already have the maximum number of toys he could have bought, so you can abort your sorting there to save some
