    Description

    After winning gold and silver in IOI 2014, Akshat and Malvika want to have some fun. Now they are playing a game on a grid made of n horizontal and m vertical sticks.

    An intersection point is any point on the grid which is formed by the intersection of one horizontal stick and one vertical stick.

    In the grid shown below, n = 3 and m = 3. There are n + m = 6 sticks in total (horizontal sticks are shown in red and vertical sticks are shown in green). There are n·m = 9 intersection points, numbered from 1 to 9.

    The rules of the game are very simple. The players move in turns. Akshat won gold, so he makes the first move. During his/her move, a player must choose any remaining intersection point and remove from the grid all sticks which pass through this point. A player will lose the game if he/she cannot make a move (i.e. there are no intersection points remaining on the grid at his/her move).

    Assume that both players play optimally. Who will win the game?

    Input

    The first line of input contains two space-separated integers, n and m (1 ≤ n, m ≤ 100).

    Output

    Print a single line containing "Akshat" or "Malvika" (without the quotes), depending on the winner of the game.

    Sample Input

    2 2

    Sample Output

    Malvika1

    Hint

    题意

    有n根横着的筷子,m根竖着的筷子,会相交出nm个交点,然后现在两个人依次玩这个游戏,每次这个人选择一个点,然后就会把穿过这个点的筷子都拿掉。

    哪个人不能操作的时候,就判断这个人输掉了。

    问最后谁会胜利。

    题解:

    取min之后,判断奇偶性就好了~

    代码

    #include<bits/stdc++.h>
    using namespace std;
    
    int main()
    {
        int n,m;
        scanf("%d%d",&n,&m);
        n=min(n,m);
        if(n%2)printf("Akshat
    ");
        else printf("Malvika
    ");
    }
