Nice-MD5s

Let's find nice patterns of MD5!!

The MD5 message-digest algorithm is a widely used hash function producing a 128-bit hash value. (Wikipedia)

This is totaly a nonsence but let's find nice patterns of MD5s.

Definitions

A nice pattern considers as one of the below:

#	Name	Explanation	Example
1	Perfect match	md5 of one characters	`00000000000000000000000000000000`
2	Nice match	md5 starts with N-same characters	`444431252d6a104a05fe4a0c6a53a999` (N=4)
3	Gold MD5	md5 of it - equal to itself	`N/A`
4	MD5 of digits	md5 contains only digits	`25855924411269249612523541155616`
5	MD5 of letters	md5 contains only letters	`abcdefabcdefabcdefabcdefabcdefab`
6	Pi MD5	md5 contains pi digits	`3141592653589793115997963468544185`
7	e MD5	md5 contains contant e digits	`2718281828459045090795598298427649`

Please see the attached Python code to run on your computer, and add a pull request if you find new one (a credit is promised!).

Feel free to add your language version of the code!
