PrefaceSome of my friends and colleagues asked me: How can the entire team's output be >2 with the increase in the number of teams? At least it is 2.In combination with my own perspective and experience, I have given some of my thoughts and

How do I quickly randomly remove 50 non-repeating elements in an array of 100 elements? Reply to discussion (solution) Array_rand ($a, 50); The array is now de-weighed, and then the random fetch can be called The array is now de-weighed,

Array_rand () is used to randomly extract one or more units from an array. It is useful to retrieve one or more random units from an array. It accepts input as an input array and an optional parameter num_req, specifying the number of units you want

What is Monkey?Monkey is a program that can run in the emulator or in the actual device . It sends pseudo-random user event streams (such as key input, touch input, gesture input, etc.) to the system, enabling stress testing of the application under

In view of the many silly questions that I often see, for example, what is the XX language used? Is the xxx language outdated? (To be honest, there are all these questions for beginners .) Here I will talk about something developers should know.

It is a very important numerical calculation method guided by probability statistics theory. A random number (or a more common pseudo-random number) is used to solve many computing problems. A Calculation Method Based on the Theory and Method of
