⭐ Introduction ⭐ ️ Hello, everyone. I'm an executive. Today we bring you a set of special training on string processing. No matter you are studying or working, you must have a lot of contact with string. If you deal with string at ordinary times, you must use library functions directly. After all, there are many library functions for strings. ...

A - Amanda Lounges Question meaning: there are n airports and m routes (the route is the side connecting two airports). For each airport, a waiting room may or may not be required. If you enter 2, both airports connected by the route need to be established, enter 1, one airport connected by the route is established (required), and enter 0, b ...

Bubble sorting The size of two adjacent elements is compared. If the current element is larger than the element on the right, it will be exchanged, otherwise it will not be exchanged; A total of N-1 rounds are arranged, and the largest element in the disordered area is selected in each round; A round needs to be compared N-1 times, and there a ...

Introduction to merge sort Algorithm idea: The core idea of merge sort is to use divide and conquer strategy to classify the sort task of the whole array into two sub problems, the first half sort and the second half sort, and then integrate the two ordered parts to complete the overall sort. That is, the array is divided into several subsequ ...

The column is used to write the basic code definitions and algorithm problems of each data structure, which is convenient for sorting out ideas. The algorithm questions in this article are mainly encountered during personal learning. Because some of them correspond in LeetCode, the question number is attached for reference & only for pers ...
