1. 直接递归 初步想法就是采用递归的方式去实现fib(n) = fib(n-1) + fib(n-2) 代码语言:javascript 代码运行次数:0 运行 AI代码解释 deffib(n):ifn==1:return0ifn==2:return1returnfib(n-1)+fib(n-2) 以n=6为例,可以看到fib(6)分解为fib(5)、fib(4),fib(5)分解为fib(4)、fib(3),fib(...

I don't understand your question, but there is one thing that can make your code run faster. If you directly compute fibonacci(n) and store the results into an array, you now have O(1) access to fibonacci(1..n). So rather than computing fibonacci 1 to n, you first calculate fibonac...
The recursion is straightforward from the code perspective, but it’s expensive from a complexity point of view. 3. Iterative Approach Now, let’s have a look at the iterative approach: fun fibonacciUsingIteration(num: Int): Int { var a = 0 var b = 1 var tmp: Int for (i in 2.....

One broad class of problem where recursion would generally be required are formula solvers. For financial models obvious examples include yield-to-maturity, implied volatility and bootstrapping (curve fitting) calculations. Here the objective is to find a solution to a model which is satisfied withi...
All tests must pass. Must use recursion. Implement memoization to store previously computed Fibonacci numbers. Handle large values of n efficiently. Return correct Fibonacci number for given input n. Tests Test calculation of Fibonacci numbers
