1. The associated container implements its own comparison type We often define a container. vector<int> vec; In fact, this is the abbreviation of the following function. vector<int, less<int>> vec; vector<int, less<int>, allocator<int>> vec; It is only the default. The default size comparison function ...

C Language Programming All code shows the code inside the main function Computer thinking Rolling-Rotating Division int u = 32; int v = 32; //If v=0, at the end of the calculation, u is the greatest common divisor //v!=0 calculates the remainder of u/v so that u=v=the remainder while(v!+0) { int temp = u%v; u = v; v = temp; } print ...

1. Are the following function definition statements correct? (a) void fun1(int i,int j); { cout<<i+j; } (b) void fun1(int i,int j) { void fun2() { cout<< "This is fun2. "<<endl; } cout<<i+j; } (c ) void fun1(int i,int j) { cout<<i+j; return 1; } (d) void fun1(int i,int j) { ...

This article will share the solution ideas and steps of LeetCode question 98 in detail, hoping to bring help to you. preface Binary tree is a very important data structure. It involves a wide range of algorithms. Whether it is an amazing backtracking algorithm or an amazing dynamic programming, it is closely related to binary tree, whic ...

Greedy algorithm (English: greedy algorithm), also known as greedy algorithm, is an algorithm that takes the best or optimal (i.e. the most favorable) choice in the current state in each step of selection, hoping to lead to the best or optimal result. Take a simple example, that is, change. For example, you need to give customers 85 yuan in cas ...

Learn more about template parameters In fact, there are three template parameters: type parameter, non type parameter and template template parameter (there is no repetition here, which is indeed the name). Chapter 12 lists examples of type parameters and non type parameters, but I haven't seen the template parameter. This chapter also has som ...

CHAPTER_6 C++STL correlation 6.3 string In the c language, we use char arrays to store strings, which can be cumbersome. Therefore, adding a string type to STL makes it easier for us to manipulate strings. To use a string, you need to add a header file #include <string>. string's usage is recorded in Algorithmic Notes P202-P209. Mo ...
