Does $2^n \gt n^2$ hold?

- $n$ is an integer between $1$ and $10^9$ (inclusive).

Input is given from Standard Input in the following format:

$n$

If $2^n \gt n^2$, print `Yes`

; otherwise, print `No`

.

5

Yes

Since $2^5=32,\ 5^2=25$, we have $2^n \gt n^2$, so `Yes`

should be printed.

2

No

For $n=2$, we have $2^n=n^2=2^2$, so $2^n \gt n^2$ does not hold. Thus, `No`

should be printed.
