"Bi Thing" Microsoft time Series algorithm--Verifying the magical Fibonacci sequence

Fibonacci numbers refer to such a sequence of 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233,377,610,987,1597,2584,4181,6765,10946,17711,28657,46368
The inventor of the Fibonacci sequence, the Italian mathematician Leonardo's Fibonacci (Leonardo Fibonacci), was born in 1170 and died in 1250, the birthplace of Pisa. He was called "the Leonardo's of Pisa". In 1202, he wrote the Book of Abacus (Liber Abacci). He was the first European to study the theory of Indian and Arab mathematics. His father, who was recruited as a diplomatic consul by a business group in Pisa, was stationed in the Algerian region today, where Leonardo's was able to study mathematics under the guidance of an Arab teacher. He has also studied mathematics in Egypt, Syria, Greece, Sicily and Provence.
