Gaming Array 1 HackerRank Solution

In this Gaming Array 1 HackerRank solution, Andy wants to play a game with his little brother, Bob. The game starts with an array of distinct integers and the rules are as follows:

  • Bob always plays first.
  • In a single move, a player chooses the maximum element in the array. He removes it and all elements to its right. For example, if the starting array , then it becomes  after removing .
  • The two players alternate turns.
  • The last player who can make a move wins.

Andy and Bob play  games. Given the initial array for each game, find and print the name of the winner on a new line. If Andy wins, print ANDY; if Bob wins, print BOB.

To continue the example above, in the next move Andy will remove . Bob will then remove  and win because there are no more integers to remove.

Problem Solution in C#

public static string gamingArray(List<int> arr)
  List<Tuple<int,int>> sortedArr = new List<Tuple<int,int>>();
  for (int i = 0; i < arr.Count; i++)
    sortedArr.Add(new Tuple<int, int>(i, arr[i]));
  sortedArr.Sort((a, b) => b.Item2-a.Item2);
  bool bobWins = false;
  int last = int.MaxValue;
  foreach (var item in sortedArr)
    var current = item.Item1;
    if (current<last)
      last = current;
      bobWins = !bobWins;
    if (last == 0)
  return bobWins ? "BOB" : "ANDY";

Problem Solution in Python

def gamingArray(arr):
    max_count = 0
    for i in arr:
        if i>maxi:
    if max_count%2!=0:
        return "BOB"
    return "ANDY"

Problem Solution in JavaScript

function gamingArray(arr) {
    var turn = -1;
    var len = arr.length;
    var limit = 0;
        var max = arr[0];
        limit = 0;
        for(var i=0;i<len;i++){
                max = arr[i];
                limit = i;
        len = limit;

        return "BOB";
        return "ANDY";
