Description:

n people are standing in a line to play table tennis. At first, the first two players in the line play a game. Then the loser goes to the end of the line, and the winner plays with the next person from the line, and so on. They play until someone wins k games in a row. This player becomes the winner.

For each of the participants, you know the power to play table tennis, and for all players these values are different. In a game the player with greater power always wins. Determine who will be the winner.

Input:

The first line contains two integers: n and k (2 ≤ n ≤ 500, 2 ≤ k ≤ 10¹²) — the number of people and the number of wins.

The second line contains n integers a₁, a₂, ..., a_n (1 ≤ a_i ≤ n) — powers of the player. It's guaranteed that this line contains a valid permutation, i.e. all a_i are distinct.

Output:

Output a single integer — power of the winner.
