http://poj.org/problem?id=2796 题意:给出n个数,问一个区间里面最小的元素*这个区间元素的和的最大值是多少. 思路:只想到了O(n^2)的做法. 参考了http://www.cnblogs.com/ziyi--caolu/archive/2013/06/23/3151556.html的写法,用单调栈可以优化到O(n). 对于每个元素,维护这个元素向前延伸比它大的有多少个,向后延伸比它小的有多少个.即该元素是处于山谷. 那么如何用单调栈维护这个呢? 首先这个栈是单调递…

http://poj.org/problem?id=3318 题意:问A和B两个矩阵相乘能否等于C. 思路:题目明确说出(n^3)的算法不能过,但是通过各种常数优化还是能过的. 这里的随机算法指的是随机枚举矩阵C的一个位置,然后通过A*B计算是否能够得到矩阵C相应位置的数,如果不等,就直接退出了,如果跑过一定的数量后能够相等,那么就可以判断这个矩阵C等于A*B的.第一次见这样的题目...有点新奇. 暴力算法: #include <cstdio> using namespace std; ][]…
