原题目: Write a recursive program that extends the range of the Fibonacci sequence.  The Fibonacci sequence is 1, 1, 2, 3, 5, 8, etc., where each element is the sum of the previous two elements. For this problem, instead of only adding the last two elem…

http://scottsievert.github.io/blog/2015/01/31/the-mysterious-eigenvalue/ The Fibonacci problem is a well known mathematical problem that models population growth and was conceived in the 1200s. Leonardo of Pisa aka Fibonacci decided to use a recursiv…

Problem Description Following is the recursive definition of Fibonacci sequence: Fi=⎧⎩⎨01Fi−1+Fi−2i = 0i = 1i > 1 Now we need to check whether a number can be expressed as the product of numbers in the Fibonacci sequence.   Input There is a number T …

For Fibonacci Sequence, the space complexity should be the O(logN), which is the height of tree. Check the source…

fibonacci数列的性质和实现方法 1.gcd(fib(n),fib(m))=fib(gcd(n,m)) 证明:可以通过反证法先证fibonacci数列的任意相邻两项一定互素,然后可证n>m时gcd(fib(n),fib(m))=gcd(fib(n-m),fib(m)),递归可 求gcd(fib(n),fib(m))=gcd(fib(k),fib(l)),最后k=l,不然继续递归.K是通过展转相减法求出,易证k=gcd(n,m),所以gcd(fib(n),fib(m)) =fib(gcd(n…

今天这篇博客就聊聊几种常见的查找算法,当然本篇博客只是涉及了部分查找算法,接下来的几篇博客中都将会介绍关于查找的相关内容.本篇博客主要介绍查找表的顺序查找.折半查找.插值查找以及Fibonacci查找.本篇博客会给出相应查找算法的示意图以及相关代码,并且给出相应的测试用例.当然本篇博客依然会使用面向对象语言Swift来实现相应的Demo,并且会在github上进行相关Demo的分享. 查找在生活中是比较常见的,本篇博客所涉及的这几种查找都是基于线性结构的查找.也就是说我们的查找表是一个线性表,我…
