### 谜题描述
|
||
Ashishgup and FastestFinger play a game.
|
||
|
||
They start with a number n and play in turns. In each turn, a player can make any one of the following moves:
|
||
|
||
* Divide n by any of its odd divisors greater than 1.
|
||
* Subtract 1 from n if n is greater than 1.
|
||
|
||
|
||
|
||
Divisors of a number include the number itself.
|
||
|
||
The player who is unable to make a move loses the game.
|
||
|
||
Ashishgup moves first. Determine the winner of the game if both of them play optimally.
|
||
|
||
Input
|
||
|
||
The first line contains a single integer t (1 ≤ t ≤ 100) — the number of test cases. The description of the test cases follows.
|
||
|
||
The only line of each test case contains a single integer — n (1 ≤ n ≤ 10^9).
|
||
|
||
Output
|
||
|
||
For each test case, print \"Ashishgup\" if he wins, and \"FastestFinger\" otherwise (without quotes).
|
||
|
||

|
||
Output
|
||
|
||
|
||
FastestFinger
|
||
Ashishgup
|
||
Ashishgup
|
||
FastestFinger
|
||
Ashishgup
|
||
FastestFinger
|
||
Ashishgup
|
||
|
||
Note
|
||
|
||
In the first test case, n = 1, Ashishgup cannot make a move. He loses.
|
||
|
||
In the second test case, n = 2, Ashishgup subtracts 1 on the first move. Now n = 1, FastestFinger cannot make a move, so he loses.
|
||
|
||
In the third test case, n = 3, Ashishgup divides by 3 on the first move. Now n = 1, FastestFinger cannot make a move, so he loses.
|
||
|
||
In the last test case, n = 12, Ashishgup divides it by 3. Now n = 4, FastestFinger is forced to subtract 1, and Ashishgup gets 3, so he wins by dividing it by 3.
|
||
|
||
Here is a reference code to solve this task. You can use this to help you genereate cases or validate the solution.
|
||
```python
|
||
import math
|
||
test_cases=int(input())
|
||
res=[]
|
||
for i in range(test_cases):
|
||
n=int(input())
|
||
t=0
|
||
while n%2==0:
|
||
n=n//2
|
||
t+=1
|
||
if t==0:
|
||
if n==1:
|
||
res.append(\"FastestFinger\")
|
||
else:
|
||
res.append(\"Ashishgup\")
|
||
elif t==1:
|
||
|

|

res.append(\"Ashishgup\")
|

a) 将当前数除以一个大于1的奇数因子

b) 当当前数>1时,减去1

无法操作的玩家失败。两人都采用最优策略。
