Problem Statement

The Kingdom of Takahashi has $N$ towns, numbered $1$ through $N$.

There is one teleporter in each town. The teleporter in Town $i$ $(1 \\leq i \\leq N)$ sends you to Town $A_i$.

Takahashi, the king, loves the positive integer $K$. The selfish king wonders what town he will be in if he starts at Town $1$ and uses a teleporter exactly $K$ times from there.

Help the king by writing a program that answers this question.

Constraints

• $2 \\leq N \\leq 2 \\times 10^5$
• $1 \\leq A_i \\leq N$
• $1 \\leq K \\leq 10^{18}$

Input

Input is given from Standard Input in the following format:

$N$ $K$ $A_1$ $A_2$ $\\dots$ $A_N$

Output

Print the integer representing the town the king will be in if he starts at Town $1$ and uses a teleporter exactly $K$ times from there.

Sample Input 1

4 5
3 2 4 1

Sample Output 1

4

If we start at Town $1$ and use the teleporter $5$ times, our travel will be as follows: $1 \\to 3 \\to 4 \\to 1 \\to 3 \\to 4$.
