题目描述

Nothing's ever been the same since... that summer with her.

— Shizuku Hoshikawa

Kaori wants to spend the day with Shizuku! However, the zoo is closed, so they are visiting Farmer John's farm instead.

At Farmer John's farm, Shizuku counts nn legs. It is known that only chickens and cows live on the farm; a chicken has 22 legs, while a cow has 44.

Count how many different configurations of Farmer John's farm are possible. Two configurations are considered different if they contain either a different number of chickens, a different number of cows, or both.

Note that Farmer John's farm may contain zero chickens or zero cows.

自从……那个与她共度的夏天之后,一切都不一样了。

——星川紫月

薰想要和紫月一起度过这一天!然而动物园关门了,于是她们转而前往约翰农夫的农场参观。

在约翰农夫的农场里,紫月数到了 nn 条腿。已知 农场里只生活着鸡和牛;一只鸡有 22 条腿,一头牛有 44 条腿。

请计算约翰农夫的农场可能有多少种不同的配置方式。若两种配置中鸡的数量不同、牛的数量不同,或两者均不同,则认为它们是不同的配置。

注意:约翰农夫的农场中可以没有鸡,也可以没有牛。

输入格式

The first line contains a single integer tt (1≤t≤1001 \leq t \leq 100) — the number of test cases.

The only line of each test case contains a single integer nn (1≤n≤1001\leq n \leq 100).

第一行包含一个整数 tt(1≤t≤1001 \leq t \leq 100)—— 测试用例的数量。

每个测试用例仅有一行,包含一个整数 nn(1≤n≤1001\leq n \leq 100)。

输出格式

For each test case, output a single integer, the number of different configurations of Farmer John's farm that are possible.

对于每个测试用例,输出一个整数,表示约翰农场的不同配置方案总数。

说明/提示

For n=4n=4, there are two possible configurations of Farmer John's farm:

  • he can have two chickens and zero cows, or
  • he can have zero chickens and one cow.

It can be shown that these are the only possible configurations of Farmer John's farm.

For n=3n=3, it can be shown that there are no possible configurations of Farmer John's farm.

当 n=4n=4 时,农夫约翰的农场有两种可能的配置:

  • 他可以养两只鸡、零头牛,或者
  • 他可以养零只鸡、一头牛。

可以证明,这些是农夫约翰的农场仅有的可能配置。

当 n=3n=3 时,可以证明农夫约翰的农场不存在任何可能的配置。

输入解题思路,AI测评打分。不知道怎么写?
