Fibonacci Sequence Formula: How to Find Fibonacci Numbers
WebJun 23, 2024 · Approach: The idea is to use the concept of Dynamic Programming to solve this problem. The concept of digit dp is used to form a DP table.. A four-dimensional table is formed and at every recursive call, we need to check whether the required difference is a Fibonacci number or not.; Since the highest number in the range is 10 18, the … WebFeb 26, 2012 · Note that. ( F n + 1 F n + 2) = ( 0 1 1 1) ( F n F n + 1) and. ( 0 1 1 1) 60 ≡ ( 1 0 0 1) mod 10. One can verify that 60 is the smallest power for which this holds, so it is the order of the matrix mod 10. In particular. ( F n + 60 F n + 61) ≡ ( F n F n + 1) mod 10. so the final digits repeat from that point onwards. WebJun 25, 2024 · The goal is to find the last digit of the n-th Fibonacci number. The problem is that Fibonacci numbers grow exponetially fast. For instance \[ F_{200} = 280 571 172 992 510 140 037 611 932 413 038 677 189 525 \] So even our iterative version will prove too slow.
