## Task

You have to write three functions namely - `PNum, GPNum and SPNum` (JS, Coffee), `p_num, g_p_num and s_p_num` (Python and Ruby), `pNum, gpNum and spNum` (Java, C#), `p-num, gp-num and sp-num` (Clojure) - to check whether a given argument `n` is a Pentagonal, Generalized Pentagonal, or Square Pentagonal Number, and return `true` if it is and `false` otherwise.

### Description




`Pentagonal Numbers` - The nth pentagonal number Pn is the number of distinct dots in a pattern of dots consisting of the outlines of regular pentagons with sides up to n dots (means the side contains n number of dots), when the pentagons are overlaid so that they share one corner vertex.


> First few Pentagonal Numbers are: 1, 5, 12, 22...

`Generalized Pentagonal Numbers` - All the Pentagonal Numbers along with the number of dots inside the outlines of all the pentagons of a pattern forming a pentagonal number pentagon are called Generalized Pentagonal Numbers.

> First few Generalized Pentagonal Numbers are: 0, 1, 2, 5, 7, 12, 15, 22...

`Square Pentagonal Numbers` - The numbers which are Pentagonal Numbers and are also a perfect square are called Square Pentagonal Numbers. 

> First few are: 1, 9801, 94109401...
 
### Examples

#### Note: 
* Pn = Nth Pentagonal Number
* Gpn = Nth Generalized Pentagonal Number
