Stream Sampler

Simple stream sampler returning a random representative sample of a specified length.

Assumptions made while implementing the solution can be found here.

Usage

mvn install
cat file.txt | ./stream-sampler -n SIZE

./stream-sampler --help
Creates a random representative sample of length SIZE out of the input.
Input is either STDIN, or randomly generated within application.
If SEED is specified, then it's used for both - sample creation and input
generation.
 -g,--generate <INPUT_SIZE>   Size of random input to generate out of
                              'abcdefghijklmnoprstuwxyz'
    --help                    Show this message
 -n,--size <SIZE>             Sample size
 -s,--seed <SEED>             Seed for random number generator
