The flash sales system is being launched recently, but the headache is that inventory problems often occur in the case of high concurrency among multiple users. It is found that multiple users place orders at the same time within the same time, causing the query and insertion to be out of sync, there is a time difference between query and insertion, which leads to inventory problems in the case of high concurrency (my project is probably like this, fi

the first element A1 of the sequence to the end: A2, a3...... an-1, an, and A1 are in the descending order of num1. Get the first Element A2 of the sequence to the end: A3, a4... an, a1, a2 at this time, number num2. ... Continuously perform the preceding operations to obtain a reverse order number each time and find the minimum number of these reverse orders. The number of reverse orders can be determine

Question: Given a sequence, the numbers in it are 0 to n-1. Each time we put the first number to the last number and repeat n times, what is the minimum number of reverse orders in N operations? Ideas: First, findInitial Number of reverse ordersAnd then move the first number to the last side, then the number of reverse orders minus the number smaller than it, plus the number larger than it. If the number I

Ides learning-use procurement orders for inter-company dump This chapter is not very good at learning, and I always feel that my thinking is messy.

If the computer to improve the efficiency of our office, will liberate handwritten delivery orders, out of the manifestPresumably many of our suppliers, distributors, as well as manufacturers, there is a problem plaguing us, is a lot of goods every day, of course, this is a good thing, it shows that business, but at the same time a lot of manifests ah, as well as the delivery order, we are all handwritten, write a line, write a dozen, which really is

easy to read and write, perfect ecosystem, cross-platform, and fast iteration is just a matter of course. What's more, the author of Guido and Python has been dug by Dropbox. Python is indeed several orders of magnitude slower than compiled languages, but it is only related to applications restricted by CPU. Dropbox is mainly subject to disk and network constraints. Therefore, the use of compiled languages does not significantly speed up Dropbox,

1. Retained stock orders Most of the continuously increasing stocks are no longer cheap, and most of them will fall or consolidate after purchase, so there is no need to consume them any more. 2. The stock price is in a downward trend and no orders are placed. This is not an absolute one, but there are three prerequisites: first, the enterprise has a good future; second, the stock price is already lower

Question:For a sequence of n numbers a1, a2,..., an, the range of these numbers is 0 ~ N-1, you can move the number of m above to the back to form a new sequence:A1, a2,..., an-1, an (where m = 0-the initial seqence)A2, a3,..., an, a1 (where m = 1)A3, a4,..., an, a1, a2 (where m = 2)...An, a1, a2,..., an-1 (where m = N-1)What is the minimum number of reverse sequences? Analysis and Summary:(1) When I first read this question, I felt familiar with it, so I read the answer record. I did = last yea

C # generate random orders based on the custom thread timer, This is because a friend asked me a question. He said that their requirement is to randomly extract data within one day to generate orders, which cannot be seen by the customer. The randomly generated order also extracts not certain State values based on the probability. According to the timer thread executor I wrote earlier, we need a timer to ex

For details about Merge Sorting, see "Introduction to algorithms"-Divide and conquer law. In the following example, we use the merge method to calculate the number of reverse orders for the 2299 questions in poj: /** The question indicates the number of exchanges that require Bubble sorting. Algorithm used: sort by merge to calculate the number of reverse orders. # This question fully demonstrates that even
