1. Valid Letter Words Given two strings s and t, write a function to determine whether t is an alphabetic ectopic word of s. Note: if each character in S and t occurs the same number of times, s and T are called alphabetic words. Valid Letter ectopic words Idea: 1. Create an array with a size of 26 to record the number of occurr ...

(the file name should also be standardized. Refer to the format of the report file) Experiment 1 linear table experiment log Implementa ...

LRU caching mechanism 1. Title Original question link Using the data structure you have mastered, design and implement an LRU (least recently used) caching mechanism. It should support the following operations: get data and write data put. Get data (key) - if the keyword (key) exists in the cache, get the value of the keyword (always pos ...

This article continues to talk about the recursive routine of binary trees.1, Determine whether the binary tree is a search binary treeSearch binary tree definition: for any subtree with X as the head in a binary tree, the left subtree is smaller than X and the right subtree is larger than x. (the classic search binary tree has no duplicate val ...

Basic concepts Edit distance issue: It is difficult to edit the distance problem, but the solution is very beautiful, and it is also a rare practical algorithmEdit the distance usage scenario: For revising the misplaced content of the article The article can only be modified by 20 words, and supports adding, deleting and replacing oper ...

Select Sorting Algorithm In order to sort the sequences with less data in ascending or descending order, we can consider using the selective sorting algorithm, whose corresponding time complexity is O(n2). The idea of sorting the sequence containing n elements by sorting algorithm is to find the maximum or minimum value from the sequence to b ...

What is a map The Map structure exists in many programming languages, including today's protagonist go language. Today, we will analyze the Map in go in several aspects. In the most popular words, Map is a data structure that obtains value through key. Its underlying storage method is array. The key cannot be repeated during storage. W ...

Huffman encoding and decoding of files 1. The global variable count conflicts with std:count. It is recommended to use other variable names.2. Memory leakage. Note that the space should be open enough that the pointer cannot cross the boundary. The stack space opened in the main function is generally 8MB. If you want to open a large array, ple ...
