How do you find the largest number in an array without sorting?

8 Answers. No need to sort, just iterate through the array, keeping track of the largest value seen so far and the index of that value. var largest = -1; var player = -1; for (var i = 0; i < allPlayers. Length; ++i) { if (allPlayers[i] > largest) { player = i; largest = allPlayers[i]; } } Console.

How do I search without sorting?

If it’s not sorted, you have to inspect each element. You can search an element with O(1) using this approach. Just create a MAP . When you insert a value just then for that key assign value to ‘1’, and to search it again just check if that array is present or not .

How to sort an array without comparison of elements?

Given an array with integer elements in small range, sort the array. We need to write a non-comparison based sorting algorithm with following assumptions about input. All the entries in the array are integers.
