给定一个数组,把每个元素当做一个矩形,宽度为1,高度为数组元素的值,求出这个数组中矩形面积最大的值。我的做法是遍历数组,给每个值找到左边比他小的值的下标,右边比他值小的下标。两个下标之间的距离即是这个矩形的宽。然后计算面积和最大面积进行比较与替换.这个算法的时间复杂度为O(n²)intlargestRectangle(vector&height){intsum=0,cursum=0;intleft

题目描述:自己想了想发现只有暴力做,但这题明显是有简便算法的,网上看了看主流的解法是用单调(递增)栈做,算法大概思想是:维护一个单调递增序列,当前元素大于栈顶元素时则进栈,当前元素小于栈定元素时则处理完前面元素能得到的最大值后在进栈。这种方法非常的巧妙,感觉应该是本题的最优解法了,比如你想用暴力做,max[i]代表从i号节点开始的最大矩形,对单个节点处理一次用时o(n),对每个节点都跑一次就要用时
