The tutorials on the web are varied and similar. I had some problems with my installation, so I summed up a blog post.Sublime text is a lightweight, cross-platform, textual editor that expands its capabilities through the package.There are a lot of packages that build the Python environment, where I install the Anaconda package.1.

blogger himself in learning machine learning process, see the related books use Python version is different, but want to each version can know how to use, next, bloggers to introduce a more simple and convenient way:
First: Install the Python environment, highly recommended to use Anaconda,anaconda is a python release, if Python is compared to Linux, then Anancoda is CentOS or Ubuntu.
The first step. Insta
Problem description: there are now n ordered arrays in M groups, such as {1, 2, 3, 4}, {2, 3, 6}, {1, 3, 5, 7 }, select the data smaller than K in these arrays and return this value.
Idea: Compare the minimum data selected each time by referring to the process of merging two Arrays
1. Define the selection position arra
Exercise 3-3 the last three bits of the productEnter several words, enter a number of integers (which can be positive, negative, or 0), and output the last three bits of their product. These integers are mixed with a string of uppercase letters, and your program should ignore them. Tip: Try to enter a string when executing scanf ("%d").#include Summary: 1 Note overflow2 for a break in the bad, the next code
Summary:Ordinary BST does not guarantee a good performance after multiple operations. So we need a BST, yes. The cost of each insertion and search is a logarithmic function of the large size of the tree. The 2-3-4 tree is a kind of BST that maintains balance.2-3-4 Tree IntroductionTo ensure that BST is balanced, we nee
BS makes it clear in C ++ programming that the variable name is more binding than the previous one.
Therefore, the following Variable declaration:Int ** a [3] [4];The two-dimensional array "[]" of the "int ** type is more binding than" int "and ). This two-dimensional array has a total of 12 members (3 × 4), each membe

Common ratios
At the beginning of the information age of 195x, the most notable feature is that analog technology has turned to digital technology, graphic design has been gradually led by electronic devices from paper to media, and the granularity units have changed, but this is not so much for designers, the problem is the ratio.
Aspect ratio, which is the height ratio, only discusses the three most common categories: photography, video, and display equipment.
