The main approach is: the first constant through the shift operation to find divisor closest to the dividend multiples, such as dividend is 100, the divisor is 3, this multiple is 32.
Then use 100 minus 3 of 32 times times, where 32 times times is generated by the left shift, and no multiplication is used.
At this point, then use a loop to find 3 times the most close to 100 and its 32 times times the differ

Title: https://oj.leetcode.com/problems/divide-two-integers/Code (GitHub): Https://github.com/illuz/leetcode :
To achieve division, you cannot use multiplication, division, and modulo. Analysis :
You can't use multiplication, divide and take modulo, the rest, plus, minus and bitwise operations. The idea is to subtract from time to time, but it will time

? A code repository, such as CVS or Subversion. The CI server queries the source code management System (SCM) repository for code modifications. When a modification is found, the CI server performs a checkout (that is, updates the local sandbox) and executes the build. In addition to executing more frequently, the build process is the same as the build that executes in the on-premises environment.

QA audit includes two major parts: process audit and product audit. process audit can include: 1) Audit of project planning activities; 2) Audit of peer audit activities; 3) review of SCM activities 4) Review of test activities 5) Audit product audits of project tracking and monitoring activities, mainly document audits ~ What to do and what to pay attention to depends on what aspects your company focuses on through QA management, or what requirements
Upgrade CDH5.2.0 to CDH5.3.3 and cdh5.2.0cdh5.3.3
The company has a Spark on Yarn cluster, which is built based on CM5.2.0 + CDH5.2.0 and the Spark version is 1.1.0. To use some features of Spark1.2.0, we decided to upgrade the cluster version to CM5.3.3 + CDH5.3.3. The reason for CM upgrade is that the version number of CM must be greater than or equal to the version number of CDH. The following two steps describe the upgrade process: CM upgrade and CDH upgrade.

Summary CVS is cool, but subversion is cooler. However, if you are using Eclipse for development, you may not be able to take advantage of subversion until recently. With the release of Subclipse, subversion may eventually overwhelm CVS by giving full power to your Eclipse IDE environment.

A simple understanding of Shares
Shares representOwnershipThe ownership includes two meanings:Interest distribution right (dividend distribution right), One isVoting rights.
First, let's look at a simple example. Suppose there are only two people in the company. These two people are both partners, start the company together, and are shareholders, each accounting for 50% of the shares.
Assuming that the company had a net profit of 1 million Yua
Population structure, commodity prices, and technological innovation are three important factors that affect the stock market cycle. The population structure has an impact period of about 50 years, and scientific and technological innovation has an impact period of about 30 years, the commodity cycle is about 30 years. Analyzing the trend of A-shares based on these three cycles will provide us with a brand new perspective on the market.
Three cycles overlap into a low point

Train of Thought 1: we can only use subtraction, minus divisor and Tots in sequence, and it definitely times out.
Idea 2: each time minus n times the divisor, the result is also added n times, so we need to increase the divisor by N times.
Extend int to long to prevent overflow.
Multi [I] stores the case where the divisor is increased by I times and then subtracte
