Sorting Bucket is a sorting algorithm that works by distributing the elements of an array into a number of buckets, and then sorting each bucket individually using another sorting algorithm. The buckets are usually implemented as arrays, and the number of buckets is typically chosen to be the same as the number of distinct elements in the input array. This algorithm is particularly useful when the input array contains a large number of elements that are uniformly distributed over a range of values. The time complexity of the algorithm is O(n+k), where n is the number of elements in the input array, and k is the number of buckets.

In China's manufacturing industry, the shortage of skilled workers is the biggest problem. This situation is particularly serious in the automotive industry.
For a long time, the shortage of skilled workers has become a big pain in China's auto quality problems.
Perhaps few people know how China's auto factories make cars. Because we often hear, see and even imagine what a certain auto plant invests in so much. In fact, everybody ignores or evades a basic question, which is how many of these investments are used to cultivate skilled skilled workers.
According to an information from a car manufacturer, an entire vehicle production line with an investment amount of RMB 1 billion has less than 600,000 yuan for the training of skilled workers. With a total production line of 2,500 workers, how much is the average training cost per worker? That is, the training cost of less than 600,000 yuan is not spent on average. Instead, it is mainly spent on the training of the team leader. The training of the general workers is much less. In fact, on the production lines of many companies, the team leader does not engage in the operation of specific work stations, and more often engages in basic management and temporary replacement work operations.
In today's auto-automation industry, the number of skilled workers required in the assembly line is the highest in automotive production processes. According to the general requirements, the assembly workers must have on-line operation certificates for professional maintenance certificates for car maintenance workers. However, the actual situation is that only about half or even fewer of the total assembly workers can meet this requirement. These workers are the most common workers in the assembly line. . Few of those seasonal workers hold professional qualification certificates for car maintenance workers because they only “recruit†when they are producing heavy tasks at the car factory, and then after only a few days of training, they can know. Put a certain part in what position, and then go online. In addition, they may be cleaners, laid-off workers, unemployed people, farmers, etc.
In a few auto companies, people are recruited into the factory almost every day, and people are dismissed every day. The operation of the auto factory production line is not affected at all.
Of course, those so-called workers also have very low wages. In the face of large-scale price cuts for cars, this has become one of the "secrets" for some auto factories to reduce costs.
The shortage of skilled workers in China's auto manufacturing industry is not a two-day event, and it has now become an important issue that restricts the development of the Chinese auto industry. However, on the one hand, car manufacturers are not willing to change this situation. In the early days when the Chinese auto industry was still in the seller’s market, few auto manufacturers had realized the importance of skilled workers, and no one would To spend too much money on the cultivation of skilled workers.
Nowadays, auto manufacturers are even more reluctant to spend money on training technical workers, because this will not only significantly increase the cost of the company, but also possibly contribute to others.
For those regular production workers, the existing technologies can basically meet the current operational requirements, and those seasonal, temporary workers, in this factory, tomorrow may arrive at another factory.
Just think, such workers can guarantee the quality of the car?
What is even more frightening is that this kind of situation will continue in a vicious cycle in the future, and auto makers will also “eat the bitter fruitâ€.
However, it is the consumer’s interest that ultimately damages. Because the high-speed mobility of the car determines the importance of its safety performance, and safety performance is essentially determined by the quality of the car.
With the approaching of October 1, the car recall system is once again receiving attention. Prior to this, the recall system training organized by the National Automobile Quality Management Center and organized by various automobile manufacturers has also ended.
According to the regulations on vehicle recall management, “defects are the same defects that are common in a batch, model, or category of products due to design, manufacturing, and other reasons. Such defects are more likely to be potential hidden dangers.†The recall is "a case of cluster failure, not accidentality."
The reality is that for consumers, the problem of the quality of cars is probably not a “batch†but a shortage of skilled workers, and individual and differential quality problems caused by assembly reasons. It should be the most realistic problem that is harder to reassure.
