Python: Fermat primality test and generating co-primes
There are a number of ways to check if a number is a prime number. Some of these are Probabilistic tests. Like the Fermat primality test.
Using Coprime integers
Groovy: substring
The substring method of a string will return a part of the string.
If given two parameters, thense defined the range of the charactes (beginning included, end excluded). If only one parameter is given this is the beginning of the substring.
The indexing is 0 based so STRING.substring(0,3) means the first 3 characters. and STRING.substring(4,7) means the charcter number, 5,6, and 7. (index 4, 5, and 6).
