Problem Statement

Takahashi turns on the light of his room at $S$ o'clock (on the $24$-hour clock) every day and turns it off at $T$ o'clock every day.
The date may change while the light is on.

Determine whether the light is on at $30$ minutes past $X$ o'clock.

Constraints

• $0 \leq S, T, X \leq 23$
• $S \neq T$
• All values in input are integers.

Input

Input is given from Standard Input in the following format:

$S$ $T$ $X$

Output

If the light is on at $30$ minutes past $X$ o'clock, print Yes; otherwise, print No.

Sample Input 1

7 20 12

Sample Output 1

Yes

The light is on between $7$ o'clock and $20$ o'clock. At $30$ minutes past $12$ o'clock, it is on, so we print Yes.

Sample Input 2

20 7 12

Sample Output 2

No

The light is on between $0$ o'clock and $7$ o'clock, and between $20$ o'clock and $0$ o'clock (on the next day). At $30$ minutes past $12$ o'clock, it is off, so we print No.

灯亮着的时候日期可能会改变。

判断$X$点过$30$分钟灯是否亮着。

约束条件

• $0 \leq S, T, X \leq 23$
• $S \neq T$
• 输入中的所有值都是整数。

输入

输入标准输入，格式如下：

$S$ $T$ $X$

输出

如果$X$点过$30$分钟灯亮着，打印Yes；否则，打印No。

样例输入1

7 20 12

样例输出1

Yes

灯在$7$点到$20$点之间亮着。在$12$点过$30$分钟时，灯亮着，所以我们打印Yes。

样例输入2

20 7 12

样例输出2

No

灯在$0$点到$7$点之间亮着，在$20$点到$0$点（第二天）之间亮着。在$12$点过$30$分钟时，灯灭了，所以我们打印No。
