参考:https://shenjie1993.gitbooks.io/leetcode-python/120%20Triangle.html 将一个二维数组排列成金字塔的形状,找到一条从塔顶到塔底的路径,使路径上的所有点的和最小,从上一层到下一层只能挑相邻的两个点中的一个。 注意点: 最好将空间复杂度控制在O(n),n是金字塔的高度 解题思路 二维DP 金字塔为:
Couple that with a mental image of the blue triangle increasing in size while the red one grows progressively narrower and you'll have a pretty good idea of how page turns work. Conclusion Before the ink was dry on this column, I thought of other useful additions to the PageTurn...

Windows Presentation Foundation (WPF) programmers sometimes use VisualBrushes to create virtual magnifying glasses like the one pictured inFigure 1. Silverlight doesn't support VisualBrush, which has led some developers to believe—even to pronounce—that it's impossible to create sim...
Note: Bonus point if you are able to do this using onlyO(n) extra space, wherenis the total number of rows in the triangle. 解析: 本题目的在于给定一个三角形矩阵,求得和最小的路径。每层只能选一个整数,上一层和下一层的整数必须是相邻的。

A triangle in 3D is specified by its three vertices (x1, y1, z1), (x2, y2, z2) and (x3, y3, z3). We cannot just draw the three straight lines defining the triangle, since that would show up as a wireframe figure. If the scene contains only a set of line segments, then ...
