Find the Winner of an Array Game.cpp

    ***********************************************************


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.
