201512: [AtCoder]ARC151 C - 01 Game
Description
Score : $600$ points
Problem Statement
There are $N$ squares called square $1$, square $2$, $\ldots$, square $N$, where square $i$ and square $i+1$ are adjacent for each $i = 1, 2, \ldots, N-1$.
Initially, $M$ of the squares have $0$ or $1$ written on them. Specifically, for each $i = 1, 2, \ldots, M$, $Y_i$ is written on square $X_i$. The other $N-M$ squares have nothing written on them.
Takahashi and Aoki will play a game against each other. The two will alternately act as follows, with Takahashi going first.
- Choose a square with nothing written yet, and write $0$ or $1$ on that square. Here, it is forbidden to make two adjacent squares have the same digit written on them.
The first player to be unable to act loses; the other player wins.
Determine the winner when both players adopt the optimal strategy for their own victory.
Constraints
- $1 \leq N \leq 10^{18}$
- $0 \leq M \leq \min\lbrace N, 2 \times 10^5 \rbrace$
- $1 \leq X_1 \lt X_2 \lt \cdots \lt X_M \leq N$
- $Y_i \in \lbrace 0, 1\rbrace$
- $X_i + 1 = X_{i+1} \implies Y_i \neq Y_{i+1}$
- All values in the input are integers.
Input
The input is given from Standard Input in the following format:
$N$ $M$ $X_1$ $Y_1$ $X_2$ $Y_2$ $\vdots$ $X_M$ $Y_M$
Output
If Takahashi wins, print Takahashi
; if Aoki wins, print Aoki
.
Sample Input 1
7 2 2 0 4 1
Sample Output 1
Takahashi
Here is one possible progression of the game.
- Takahashi writes $0$ on square $6$.
- Aoki writes $1$ on square $1$.
- Takahashi writes $1$ on square $7$.
Then, Aoki cannot write $0$ or $1$ on any square, so Takahashi wins.
Sample Input 2
3 3 1 1 2 0 3 1
Sample Output 2
Aoki
Since every square already has $0$ or $1$ written at the beginning, Takahashi, who goes first, cannot act, so Aoki wins.
Sample Input 3
1000000000000000000 0
Sample Output 3
Aoki
