Handling Standard Signals #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <signal.h> void signal_handler(int sig_num) { if (sig_num == SIGINT) { printf("Ctrl+C signal received\n"); } } int main(void) { // Set SIGINT to be ignored if (signal(SIGINT, SIG_IGN) == SIG_E ...

Data Serialization Fundamentals Auotmated data collection systems rely heavily on standardized interchange formats to move information between network requests, local caches, and persistent storage layers. Two widely adopted approaches for structuring extracted payloads are JavaScript Object Notation (JSON) and Comma-Separated Values (CSV). JSO ...

Permutations This article demonstrates a method for generating all permutations of a set of numbers using depth-first search (DFS). #include <iostream> #include <vector> #include <algorithm> using namespace std; const int MAX_SIZE = 100010; int size, sequence[MAX_SIZE]; bool visited[MAX_SIZE]; void generatePermutations(int ...

The problem involves verifying the presence of a closed loop within a sequence of connected nodes. Specifically, one must determine if traversing the next pointers eventually returns to a previously encountered node. While test environments may define connection indices for simulation purposse, the algorithm operates logically without reliance ...

Regular expressions (regex) serve as a powerful mechanism for identifying and extracting specific patterns within large blocks of text. In the context of web scraping, regex allows developers to parse HTML source code to retrieve specific data points such as URLs, email addresses, or meta tags without the overhead of a full DOM parser. Core Com ...

Function Expressions vs Function Declarations JavaScript provides two primary ways to define functions: function declarations and function expressions. While both approaches create callable functions, they behave differently in terms of hoisting and usage patterns. Function Declarations A function declaration uses the function keyword to define ...
