As we all know, Excel is the master of data calculation and analysis, our daily life when we use Word, there is a need to calculate the data in the Word table, we think of using an Excel spreadsheet to process, and then fill the data into the corresponding cells, but we also understand that If you use an Excel spreadsheet to calculate this data one by one, once the data needs to be modified, we need to rewo

I used to take a written test. One of the questions in the test was to calculate the number of times that 1 appeared within 40 billion. At that time, I only gave the idea. The specific implementation was not written. Now I will list the specific implementation code. The following code can only calculate the number less than the N power of 10, instead of the x * 10 ^ N power. To expand the calculation, we al

This article describes how to calculate the difference in days between two dates in javaScript (sample code ). 1. Calculate the number of days when the two dates are different. For example:Str1 = "2002-01-20"Str2 = "2002-10-11"How does one use javaScript to calculate the number of days between str1 and str2? The Code is as follows:

In python, The datetime module can be used to conveniently calculate the difference between two time points. The unit of datetime time difference can be days, hours, seconds, or even microseconds, let's take a closer look at the powerful functions of datetime. I wrote something today to calculate the time difference. I remember it was written last year. So I mark it again today to avoid forgetting it. In

If I already know the year and the week of the year (52 weeks in a year), calculate the initial date and end date of the week. The Code is as follows: 1 functionGetWeekDate ($ year, $ week) 2 {3 $ monthsarray (1Jan ., 2Feb ., 3Mar ., 4Apr ., 5May ., 6Jun ., 7Jul ., 8Aug. If I already know the year and the week of the year (52 weeks in a year), calculate the initial date and end date of the week. The Code is

How to calculate the code running performance and the code running performance During the development process, a function may have multiple implementation methods. To pursue code performance, we often need to compare the running time of each implementation method, so as to select the best performance implementation method. So how can we calculate the running time of a piece of code (or function)? This is wh

results, 0 1 4 9 5 exchanged 2 times, is equal to the number of 4 reverse orders. 4th bubble results, 0 1 4 5 9 exchanged once, is equal to the number of 5 reverse orders. 5th bubble results, 0 1 4 5 9 exchanged 0 times, it is equal to the number of 9 reverse orders. 2 + 1 + 2 + 1 + 0 = 6 So the problem is to find the reverse order of the array? Therefore, we only need to traverse each bit, calculate the number of reverse orders for each bit, and sum

How many lines of source code will be mentioned in some books on Software Engineering. for example, projects with 1 million lines of code and 100,000 lines of code may adopt different management methods. so I want to know how many lines of code I have participated in. but when I asked my colleagues, I was not quite clear about it. It may look like hundreds of thousands or even millions of people. this is too inaccurate. so I thought of writing some code to c
