Tou Ge Algorithm Design and Analysis: Addition, Subtraction, Multiplication and Division of Large Integers
Level 1: Addition, subtraction, multiplication and division of large integers Task description The task of this level: Master the basic idea of large integers, and use the basic operations of large integers to calculate the factorial of a conventional integer n, and then count the number of digits 0 in the large integer n!. Related […]
Integer and Object
36.Integer a= 127,Integer b = 127;Integer c= 128,Integer d = >128;, are they equal? the answer is a and b equal, c and d not equal. For basic data types = = ?Compared value For index data types = = ?What’s more important is the address Integer a= 127 This kind of assignment, is it? […]
CVE-2023-0179-Nftables integer overflow
Foreword Netfilter is a network packet filtering framework for Linux operating systems that provides a flexible way to manage the flow of network packets. Netfilter allows system administrators and developers to control how data packets are processed in the Linux kernel to implement network security, Network Address Translation (NAT), packet filtering and other functions. Cause […]

In order to improve search efficiency, a database constructs a binary search tree (BST) for a certain integer field.
Disclaimer: The following method is not necessarily correct. It was written during personal study and has not been tested extensively. It is for reference only. There may be bugs and will not be changed for the time being. Description: In order to improve search efficiency, a database constructs a binary search tree (BST) for a […]
[C++ Code] Climbing stairs, different paths, integer splitting, different search trees, dynamic programming–Code Thoughts
Dynamic programming, English: Dynamic Programming, referred to as DP, if a certain problem has many overlapping sub-problems, using dynamic programming is the most effective. Therefore, each state in dynamic programming must be derived from the previous state. This is different from greed. Greedy does not have state derivation, but directly selects the optimal one from […]
c Question 1: Read an integer number from the keyboard, calculate how many digits the number has, and print out the number in each digit.
Read an integer number from the keyboard, count how many digits the number has, and print out the number in each digit. Loop and remainder operator (pow) Because we need to use pow, we need to add #include to introduce the math library. Start writing code #include <stdio.h> int main() { int num, count = […]
Use C++ to design n integer matrices M1..Mn for continuous multiplication. The dimension of each matrix is between 1-200, the number of matrices n is between 5-180, and the matrix elements are non-negative integers of at most 2 digits. Each matrix The sum result matrix is stored in the form of a text file with the file name M1…

[JAVA] Large integer multiplication (divide and conquer method)
Table of Contents Introduction Algorithm ideas Improve ideas Specific implementation ideas Supplementary ideas Complete code statement Introduction Large integer multiplication is a method for computing the multiplication of two very large integers, often beyond what computer hardware can handle directly. In this case, we need to use some special algorithms to deal with this type […]
