How to implement common sorting algorithms in C++?
In the field of computer science, sorting algorithm is an important technology, which is widely used in various scenarios. By sorting the data, the data can be made more orderly, which is convenient for subsequent processing and analysis. This article will introduce several commonly used sorting algorithms, and give the corresponding C++ code implementation.
Selection Sort
Selection sort is a simple and intuitive sorting algorithm. Its basic idea is to select the smallest (or largest) element from the data to be sorted each time and put it at the end of the sorted data. The time complexity is O(n²), and the space complexity is O(1).
void selectionSort(int arr[], int n)

for (int i =
