The Hamming distance between two integers is the number of positions at which the corresponding bits are different.

The demons had captured the princess (P) and imprisoned her in the bottom-right corner of a dungeon. The dungeon consists of M x N rooms laid out in a 2D grid. ...

You are given an array x of n positive numbers. You start at point (0,0) and moves x[0] metres to the north, then x[1] metres to the west, x[2] metres to the so...

Given N axis-aligned rectangles where N > 0, determine if they all together form an exact cover of a rectangular region.

Given a triangle, find the minimum path sum from top to bottom. Each step you may move to adjacent numbers on the row below.

A robot is located at the top-left corner of a m x n grid (marked ‘Start’ in the diagram below).

这一节我们主要谈一些二阶方法——内点法（Interior Method），如果还有空位的话，还会简单引入一下近端牛顿方法（Proximal Newton Method）。你可能要问明明只有一个方法，为什么要用“一些”？这是因为内点法其实是一种方法的总称，...

某些特殊的应用场合可能要求PCIe设备能够以高可靠性持续不间断运行，为此，PCIe总线采用热插拔（Hot Plug）和热切换（Hot Swap）技术，来实现不关闭系统电源的情况下更换PCIe卡设备。...
