The problem is asking to determine the winner of the game Nim. The game Nim is a mathematical game of strategy in which two players take turns removing objects from distinct heaps or piles. On each turn, a player must remove at least one object, and may remove any number of objects provided they all come from the same heap or pile. The goal of the game is to avoid being the player who must remove the last object.

Here is a step-by-step solution:

Step 1: Understand the problem. The problem is asking to determine the winner of the game Nim. The game Nim is a mathematical game of strategy in which two players take turns removing objects from distinct heaps or piles. On each turn, a player must remove at least one object, and may remove any number of objects provided they all come from the same heap or pile. The goal of the game is to avoid being the player who must remove the last object.

Step 2: The key to solve this problem is understanding the concept of "Nim-Sum". The Nim-Sum is calculated by taking the binary representation of the size of each pile, and performing the bitwise XOR operation on them. If the Nim-Sum is 0, then the first player will lose if both players play optimally. If the Nim-Sum is not 0, then the first player will win if both players play optimally.

Step 3: Implement the solution. First, read the number of piles. Then, read the size of each pile. Calculate the Nim-Sum by performing the bitwise XOR operation on the size of each pile. If the Nim-Sum is 0, print "Player 2". Otherwise, print "Player 1".

Here is a Python code snippet that implements the above steps:

```python
n = int(input())
piles = list(map(int, input().split()))
nim_sum = 0
for pile in piles:
nim_sum ^= pile
if nim_sum == 0:
print("Player 2")
else:
print("Player 1")
```

This code first reads the number of piles and the size of each pile. It then calculates the Nim-Sum by performing the bitwise XOR operation on the size of each pile. If the Nim-Sum is 0, it prints "Player 2". Otherwise, it prints "Player 1".
