LeetCode notes: greedy algorithm
Since the University, I have been learning some algorithms and data structures one after another. At the same time, I also began to brush questions on some platforms and participate in some algorithm competitions, large and small. However, the lack of purposefulness and systematicness of problem brushing at ord ...
This Blog continues to learn about structural patterns and how to more gracefully layout classes and objects. Structural patterns describe how to combine classes or objects according to a certain layout in order to obtain a better and more flexible structure. Although the object-oriented inheritance mechanism provides the most basic function of ...

In MATLAB, there is a very useful function reshape, which can reshape a matrix into another new matrix of different sizes, but retain its original data. A matrix represented by a two-dimensional array and two positive integers r and c are given to represent the number of rows and columns of the matrix to be reconstructed res ...

Simple insert sort
Start from the second element of the array and compare it forward in turn. If the previous element is large, move it back. Repeat array length - 1 round. The working principle is to build an ordered sequence, scan the unordered data from back to front in the sorted sequence, find the corresponding position and insert it.
Algo ...

1, Problem description
Find the value of the expression according to the inverse Polish representation. Valid operators include +, -, *, /. Each operand can be an integer or another inverse Polish expression.
Note: integer division only retains the integer part; The given inverse Polish expression is always valid. In other words, an expressio ...

strand (1) String is a finite sequence of zero or more characters, also known as string. The value of a string can be a number, letter, or other character. (2) The number of characters in the string is called the length of the string, and the string with zero characters is called an empty string with a length of 0 (3) The subsequence composed o ...

1.P2758 edit distance Linear dp
The main difficulty of this problem is how to convert these three steps into state transition. First, we determine the state first, because there are two strings to match. First, we will think of the longest common subsequence problem. Because a main string a needs to be matched into b, then each substring of ...
