Fibonacci Sequence

Problem

Start with a pair of rabbits (one male and one female) born on January 1. Assume that all months are of equal length and that:

• The first pair of rabbits reproduced two months after their own birth.

• After two months of age, each pair produces a mixed pair (one male and one female), and then another mixed pair every month.

• No rabbit dies.

Find out how many pairs will there be at the end of each month of the first year. Store the numbers in an array called array.
