Asymptotic Analysis of Recursive Functions —— Substitution Method

In my last post, I wrote some basic concepts about Asymptotic Analysis. However, how can we analyze the recursive functions? In fact, there 3 ways that we often can use.

Substitution Method

In some simple cases, we can use this method. Let's say we want to find out the upper bound of this recursive function:...

Orz=3 一不小心就把这个网站的的网址给改了……

      这系列的作品真的很精彩,可以说是“大开眼界”。你能从这作品中学习到很多物理学知识,而且还能感受到“原来还能这么用”的感觉。剧情紧凑,而且虽然每次汤川学招牌随便找东西写公式和托眼镜夸张,但在表现力却很有画面感。和其他的推理作品一样,每一集都有各种的明星客串做当集的人物(苍老师也做过死者-_,-)。...
