Given a triangle, find the minimum path sum from top to bottom. Each step you may move to adjacent numbers on the row below. For example, given the following triangle [ [], [,4], [6,,7], [4,,8,3] ] The minimum path sum from top to bottom is 11 (i.e.,…

题意:给一个用序列堆成的三角形,第n层的元素个数为n,从顶往下,每个元素可以选择与自己最近的两个下层元素往下走,类似一棵二叉树,求最短路. [], [,4], [6,,7], [4,,8,3] 注意:这里可以2->3>5>1,也可以2->4>5->1,隔层相邻就可以走. 思路:可以从下往上走,也可以从上往下走.都是O(n)的空间,平方阶的复杂度. 从下往上可能更简洁,因为比较到最后只有一个元素,就是为答案了,速度自然也就快,每遍历一层就有1个被淘汰. 然而我一开始想到的…
