题意:给出n个矩形的高,问它们能组成的最大矩形的面积是多少。
思路:定义两个数组 l[i] 和 r[i] ,分别记录从 i 点能向左向右扩展的最大位置。若a[i]<=a[ l[i] - 1 ],则 l[i] = l[ l[i] - 1](如果i可以扩展到l[i]-1处,那么在计算i之前l[i]-1处的l[l[i]-1]已经计算出来了,就可以直接令l[i]=l[l[i]-1]了);同理,若 a[i]<=a[ r[i] - 1 ],则 r[i] = r[ r[i] - 1]。这样做充分利用了之前已经计算出来的数...

题目这个题目是我在写 LeetCode Largest Number 的时候看到的题目.题目意思是给你一组数字,例如:
[3, 30, 34, 5, 9]
那么所能拼成的最大数字应该是:
9534330
解题思路其实这个题目我们很容易发现,就是把数字按照我们想要的大小排序就好了。先看如何比较,通常我们的想法应该是直接比较,或者按照位比较。可是那样情况就太多了,例如:a=3; b=4很容易得出...
