Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand.
There are N children standing in a line. Each child is assigned a rating value.
Given a positive integer n and you can do operations as follow:
Given a triangle, find the minimum path sum from top to bottom. Each step you may move to adjacent numbers on the row below.
Given two words word1 and word2, find the minimum number of steps required to convert word1 to word2. (each operation is counted as 1 step.)
Given an array of non-negative integers, you are initially positioned at the first index of the array.
Filter（筛选法）通过分析特征子集内部的特点来衡量特征的分类能力，与后面的采用何种分类器无关，这类方法通常需要评价特征相关性的评分函数和阈值判别法来选择出得分最高的特征子集。通过文献调研，根据选择特征子集方式的不...
一个4输入a, b, c, d和一输出的逻辑电路，当输入为2， 7或15时，输出为1， 当输入为0, 1, 4, 5, 6, 9, 10, 13, 或 14 时，输出为0，当输入为3，8，11或12时输出为任意值。举例来说，7对应输入abcd为0，1，1，1....
由于EasyNVR视频平台分为软件版本和硬件版本的智能云终端，因此用户可以根据自身需求选择。根据某位用户的要求，需要在EasyNVR智能云终端中增加控制矩阵功能，因此我们在EasyNVR硬件内测试通过串口通信控制矩阵，但是在打开...
