<p>For those of you turning your attention to collatz, I really
encourage you to take a look at the Online Encyclopedia of Integer
Sequences.</p>

<p>and then run your program on the interval 1-72 to see if you are
producing the correct output. Remember that if two integers have
the same collatz sequence length, you keep the smaller integer in
your list. When I run my code using those limits I produce the
following...</p>

<p>I could potentially run you programs with a really big ranges or
really big numbers (largest being 2100000000). <br>
