AT_abc467_a [ABC467A] Obesity

The value calculated by the following formula is called $ \mathrm{BMI}[\mathrm{kg}/\mathrm{m}^2] $ . ( $ \div $ denotes division.) - $ \text{Weight}[\mathrm{kg}] \div \text{Height}[\mathrm{m}] \div \text{Height}[\mathrm{m}] $ In Japan, a person whose $ \mathrm{BMI} $ is $ 25 \; \mathrm{kg}/\mathrm{m}^2 $ or more is considered obese. Determine whether a person with height $ H[\mathrm{cm}] $ and weight $ W[\mathrm{kg}] $ is considered obese in Japan.

The input is given from Standard Input in the following format: > $ H $ $ W $

Output `Yes` on one line if a person with height $ H[\mathrm{cm}] $ and weight $ W[\mathrm{kg}] $ is considered obese in Japan, and `No` otherwise.

### Sample Explanation 1 Since the height is $ 180 \; \mathrm{cm}=1.8 \; \mathrm{m} $ , the $ \mathrm{BMI} $ is $ 60 \; \mathrm{kg} \div 1.8 \; \mathrm{m} \div 1.8 \; \mathrm{m}=18.5\dots \; \mathrm{kg}/\mathrm{m}^2 $ , so this person is not considered obese. ### Constraints - $ 1 \leq H \leq 300 $ - $ 1 \leq W \leq 300 $ - All input values are integers.
