【算法数据结构Java实现】时间复杂度为O(n)的最大和序列

今天看到了一种时间复杂度只为O(n)的解题算法，在这里记录下。思路很简单，比方说有P1,P2,P3,P4.这样一个序列，我们从P1开始求和，比如说在P5时求和数小于零，就可以断定。第一种情况，最大序列在P1~P5之间，或者说在P6~Pn之间。因为如果P1...

【算法数据结构Java实现】递归的简单剖析及时间复杂度计算

时间复杂度计算以上题为例，将f(x)=f(x-1)+x/(4*x)展开，将f(x)乘以4相减，得,设4的x方等于k，则原式时间复杂度，log以4为底。参考：http://blog.csdn.net/budapest/article/details/6367973 /*本文来自博客“李博Garvin“*转载请标明出处...
