Leonardo Pisano (Fibonacci) pondered the question: How many pairs of rabbits can be produced from a single pair of rabbits, in one year, under optimal conditions (none die, and the females always gives birth to one male and one female)? Rabbits must be one month old to reproduce, so only one pair exists again at the beginning of the 2^{nd }month. At the end of the 2^{nd} month, the female gives birth, leaving 2 pairs of rabbits at the beginning of the 3^{rd} month. At the end of the 3^{rd} month, the original pair produce another pair of newborns (while their earlier offspring mature), leaving 3 pairs to start the 4^{th} month. The Fibonacci sequence is:
{1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ...},
where each entry represents the number of pairs of rabbits at the beginning of each month.
