13.5 dynamic memory management class The best way to manage dynamic memory in a class is to use containers or smart pointers, but maybe if we want to design a set of libraries ourselves, we need to keep the performance of this library at a better level. At this time, we may need to use some lower leve ...

Aggregation operation of java collection Step 1: traverse data in the traditional way and aggregate operation way The traditional way of traversing data is to use the for loop, then judge the conditions, and finally print out the data that meets the conditions for (Hero h : heros) { if (h.hp > 100 && h.damage < 50) System ...

From today on, I want to sum up again what java has to do with collections. It's convenient for me to review. Besides, spring moves are also here. It's terrible. I want to learn them seriously. I can't learn from the epidemic. It's beautiful. Well, there's no more nonsense. Let's take a look at a pictur ...

1. difflib difference calculation tool This module provides classes and functions for comparing sequences. For example, it can be used to compare files and produce different information in various formats, including HTML and context, as well as differences in uniform formats. For a comparison of directories and files, see the filecmp module. cl ...

It has been said that the power of DL lies in its fitting ability. As long as you can give the curve, its equation can be expressed by a set of neural network. However, this set of neural network needs enough data for training, which leads to the concept of over fitting and under fitting. When the neur ...

(1) Anonymous function You can use anonymous functions when you don't want to display the defined functions. 1 def f(x): 2 return x*x 3 4 #Assign anonymous functions to a variable 5 result = lambda x:x*x 6 7 print(result(5)) 8 print(f(5)) From the output, we can see that lambda x:x*x is actually: 1 def f(x): 2 return x*x The lambd ...
