Python homework Lesson 1 and python Lesson 1
I started learning from scratch. Recently, all the students around me are learning. I also want to try it. Hey, I'll write it down. I can come and see it next time I don't remember it ~~
Python

algorithm (II): mainly introduces graph application and PageRank algorithm
3. PageRank algorithm: Principle, others.
4. Open Course on Algorithms and excellent books: Algorithms, 4th Edition (download), and introduction to Algorithms
Job Requirements1. Ask the students from the school committees to complete their homework.

To get this topic, we will first think of using loops to complete.But not every operator is a "+" sign.Therefore, we are here to use (-1) of the I-side to do "+" "-" number control.The loop variable i is then treated as the denominator.Here we have the idea of the loop body is basically OK.It is important to note that the calculation results here are expressed in decimals, so it is not possible to define variables with int integers.The code is as foll

Note: When calculating 1 to use a double type that is 1.0 .
Odd even numbers are calculated separately and then merged.
#include
Label control +1,-1 with flag.
#include
Use the Function Pow Pow ( -1,i+1) equivalent ( -

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 ti

#include Be careful to define its type, divide it into two parts, and define it as "I" to see if the denominator is an odd or even number, and the sum is summed. C language: Calculate 1/1-1/2+1/3-1/

Lesson 4 MongoDB Data Query (1): mongodb Data Query1. Course outlineThis course mainly describes MongoDB Data Query related content, including the introduction and use of the find function, query operator introduction and use, embedded document query, and array query. 1. Introduction and use of the find function 2. int

, the_number is set to 4.
After setting the parameters, we enter the function body. Because 4 is less than 10, the_number is changed to "04", and the the_number value is returned using the return command. After "04" is returned by fixNumber, in this example, fixed_minute is equal to "04 ".
We will study this process step by step. Assume that the time is 12:04:05.
We start with the announceTime () function.

There are many formulas for calculating pi pai in history, in which Gregory and Leibniz found the following formula:
Pai = 4* (1-1/3+1/5-1/7 ...)
The formula is simple and graceful, but in a bad way, it converges too slowly.
