Introduction
The birth of this article was accidental.
That’s what happened:
- Today I want to speed up pure Python program
- I found that I can do it with CPython
- I need a test case to test CPython program
- I thought of Fibonacci
- I need answers to check program is correct
After I checked, many resources on the Internet provided standard answers ranging from 0 to 10. However, I hope to have more answer to ensure my program can be more accurate.
Finally, I found a great website: http://oeis.org/A000045/b000045.txt
In order to make it easier for me to check back in the future and note to forget this URL, I decided to record it in my blog.
