9537: ABC238 —— A - Exponential or Quadratic
[Creator : ]
Description
Does $2^n \gt n^2$ hold?
Input
Input is given from Standard Input in the following format:
```
$n$
```
```
$n$
```
Output
If $2^n \gt n^2$, print `Yes`; otherwise, print `No`.
Constraints
- $n$ is an integer between $1$ and $10^9$ (inclusive).
Sample 1 Input
5
Sample 1 Output
Yes
Since $2^5=32, 5^2=25$, we have $2^n>n^2$, so Yes should be printed.
Sample 2 Input
2
Sample 2 Output
No
For n=2, we have $2^n=n^2=2^2$, so $2^n>n^2$ does not hold. Thus, No should be printed.
Sample 3 Input
623947744
Sample 3 Output
Yes
