Climbing Stairs

 

You are climbing a stair case. It takes n steps to reach to the top.

Each time you can either climb 1 or 2 steps. In how many distinct ways can you climb to the top?

简单题目,相当于fibonacci数列问题,难点就是要会思维转换,转换成为递归求解问题,多训练就可以了。

所以这种类型的题目相对于没有形成递归逻辑思维的人来说,应该算是难题。

我的想法是:

每次有两种选择,两种选择之后又是各有两种选择,如此循环,正好是递归求解的问题。

写成递归程序其实非常简单,三个语句就可以:
