1535 - Find the Winner of an Array Game.

Medium

Given an integer array arr of distinct integers and an integer k.

A game will be played between the first two elements of the array (i.e. arr[0] and arr[1]). In each round of the game, we compare arr[0] with arr[1], the larger integer wins and remains at position 0, and the smaller integer moves to the end of the array. The game ends when an integer wins k consecutive rounds.

Return the integer which will win the game.

It is guaranteed that there will be a winner of the game.

Example 1:

Input: arr = [2,1,3,5,4,6,7], k = 2

Output: 5

Explanation: Let’s see the rounds of the game:

 Round | arr | winner | win_count
     1 | [2,1,3,5,4,6,7] | 2 | 1 
     2 | [2,3,5,4,6,7,1] | 3 | 1 
     3 | [3,5,4,6,7,1,2] | 5 | 1 
     4 | [5,4,6,7,1,2,3] | 5 | 2 

So we can see that 4 rounds will be played and 5 is the winner because it wins 2 consecutive games.

Example 2:

Input: arr = [3,2,1], k = 10

Output: 3

Explanation: 3 will win the first 10 rounds consecutively.

Constraints:

  • 2 <= arr.length <= 105
  • 1 <= arr[i] <= 106
