## Challenge #123: When will Rabbits Rule the World?

This is a good one, thanks @OllieClarke for help with debugging!

Turned out some of my issues were due to considering rabbits aged 4 months to be already in reproductive age, once I changed that, I got the right month, although my numbers are a bit off...

Another issue was the wrong data type which ended up with loads of nulls!

Struggled initially because I was interpreting it as >=4 rather than >4 for the age at which rabbits start producing! Definitely not the most efficient solution as it took 5 mins to run, but good iterative macro practice nonetheless!

Slightly different number for humans -- didn't floor after each month, rather calculated from starting values each time

I'm still learning how to build macros, so I'm not sure I should full credit for this.

All props to @acrahen's solution since I had to walk myself through step by step:

I did however choose my own icon ('tis the little things) ;)...
