""" 1000-digit Fibonacci number
The Fibonacci sequence is defined by the recurrence relation:
Fn = Fn−1 + Fn−2, where F1 = 1 and F2 = 1.
Hence the first 12 terms will be:
1 2 3 4 5 6 7 8 9 10 11 12
(1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144)
The 12th term, F12, is the first term to contain three digits.
What is the index of the first term in the Fibonacci sequence to contain 1000 digits?
