预测硬币游戏的赢家
有两个玩家 P1 和 P2 以及两堆分别由 M 和 N 硬币组成的硬币。在每个回合中，玩家只能从这些堆中选择一堆，并丢弃另一堆。这个丢弃的堆不能在游戏中进一步使用。堆玩家选择的进一步分为两堆非零部分。不能分堆即堆中硬币数为< 2 的玩家，输掉游戏。任务是确定如果 P1 开始游戏并且两个玩家都以最佳状态玩游戏，哪个玩家获胜。 举例:
输入: M = 4，N = 4 输出:玩家 1 玩家 1 可以选择任意一堆，因为两者包含相同数量的硬币 然后将选择的一堆(未选择的一堆被丢弃)分成两堆，每堆 1 枚硬币。 现在，玩家 2 没有移动(因为剩余的两堆都包含一枚硬币 ，不能分成两组非零硬币)。 输入: M = 1，N = 1 输出:玩家 2 无招可使。
方法:只需检查任意一堆硬币是否由偶数硬币组成。如果是，则玩家 1 获胜，否则玩家 2 获胜。 以下是上述办法的实施情况:
C++
// C++ implementation of the approach
#include <bits/stdc++.h>
using namespace std;
// Function to print the winner of the game
void findWinner(int M, int N)
{
if (M % 2 == 0 || N % 2 == 0)
cout << "Player 1";
else
cout << "Player 2";
}
// Driver code
int main()
{
int M = 1, N = 2;
findWinner(M, N);
return 0;
}
Java 语言(一种计算机语言，尤用于创建网站)
// Java implementation of the approach
import java.io.*;
class GFG {
// Function to print the winner of the game
static void findWinner(int M, int N)
{
if (M % 2 == 0 || N % 2 == 0)
System.out.println("Player 1");
else
System.out.println("Player 2");
}
// Driver code
public static void main(String[] args)
{
int M = 1, N = 2;
findWinner(M, N);
}
}

Python 3
# Python implementation of the approach
# Function to print the winner of the game
def findWinner(M, N):
if (M % 2 == 0 or N % 2 == 0):
print("Player 1");
else:
print("Player 2");
# Driver code
M = 1;
N = 2;
findWinner(M, N);
# This code contributed by PrinciRaj1992
C
// C# implementation of the approach
using System;
class GFG {
// Function to print the winner of the game
static void findWinner(int M, int N)
{
if (M % 2 == 0 || N % 2 == 0)
Console.WriteLine("Player 1");
else
Console.WriteLine("Player 2");
}
// Driver code
static public void Main()
{
int M = 1, N = 2;
findWinner(M, N);
}
}

服务器端编程语言（Professional Hypertext Preprocessor 的缩写）
<?php
//PHP implementation of the approach
// Function to print the winner of the game
function findWinner($M, $N)
{
if ($M % 2 == 0 || $N % 2 == 0)
echo "Player 1";
else
echo "Player 2";
}
// Driver code
$M = 1;
$N = 2;
findWinner($M, $N);
// This code is contributed by Tushil.
?>
java 描述语言
<script>
// Javascript implementation of the approach
// Function to print the winner of the game
function findWinner(M, N)
{
if (M % 2 == 0 || N % 2 == 0)
document.write(("Player 1"));
else
document.write(("Player 2"));
}
// Driver code
var M = 1, N = 2;
findWinner(M, N);
// This code is contributed by rutvik_56.
</script>
Output:
Player 1
