WebThe most efficient one is probably the one based on matrix exponentiation ([[1, 1], [1, 0]], IIRC), which requires Theta(lg(n)) matrix multiplications (and is what you do in Dijkstra's algorithm).Of course, that doesn't take into account the cost of arithmetic operations, which is definitely not O(1) in this case. I don't think addition can be sub lg(n) [where n is the … WebOne among very common questions asked in maths category in competitive programming is Fibonacci Series.
