AT_abc461_a.Armor

Takahashi is wearing armor.

This armor blocks all attacks with power (strength represented as an integer) of $D$ or less, but does not block attacks with power greater than $D$.

Does this armor block an attack with power $A$?

高桥正在穿着盔甲。

该盔甲可以阻挡所有攻击力（以整数表示的强度）不超过 $D$ 的攻击，但无法阻挡攻击力大于 $D$ 的攻击。

该盔甲能否阻挡攻击力为 $A$ 的攻击？

The input is given from Standard Input in the following format:

$A$ $D$

输入从标准输入中按以下格式给出：

$A$ $D$

Output Yes if the armor blocks the attack, and No otherwise.

如果护甲能阻挡攻击，则输出 Yes，否则输出 No。

Sample 1 Explanation:
In this sample, $A = 4$ and $D = 5$. Since $A = 4$ is at most $D = 5$, the armor blocks the attack, so the answer is Yes.

Sample 2 Explanation:
In this sample, $A = 5$ and $D = 5$. Since $A = 5$ is at most $D = 5$, the armor blocks the attack, so the answer is Yes.

Sample 3 Explanation:
In this sample, $A = 6$ and $D = 5$. Since $A = 6$ is not at most $D = 5$, the armor does not block the attack, so the answer is No.

Constraints

• $1 \leq A \leq 100$
• $1 \leq D \leq 100$
• All input values are integers.

样例 1 解释：
本样例中，$A = 4$ 且 $D = 5$。由于 $A = 4$ 不超过 $D = 5$，护甲可阻挡此次攻击，因此答案为 Yes。

样例 2 解释：
本样例中，$A = 5$ 且 $D = 5$。由于 $A = 5$ 不超过 $D = 5$，护甲可阻挡此次攻击，因此答案为 Yes。

样例 3 解释：
本样例中，$A = 6$ 且 $D = 5$。由于 $A = 6$ 超过了 $D = 5$，护甲无法阻挡此次攻击，因此答案为 No。

限制条件

• $1 \leq A \leq 100$
• $1 \leq D \leq 100$
• 所有输入值均为整数。
