Refrigerator and Air Conditioner (AC) are both electrical appliances that are used to reduce the temperature of a closed space by transferring the heat of the closed space to another place. Both AC and refrigerator work on the principle of heat-sinks, i.e., these devices transfer the heat from a source (or closed space) to another place called sink. Read through this article to find out how Air Conditioners are different from Refrigerators. What is an Air Conditioner? An Air Conditioner is an electrically operated cooling device which is generally used to cool a large closed space such as a ... Read More
The re module provides tools while working with Python's regular expression (regex), which allows us to search for any specific pattern within the strings. Using the 're' module provides two functions named match() and search(), which accept a pattern (regular expression) and return True or False. The match() function returns 'None' if no pattern is detected, or it returns the match in the form of an object (in case of a match). In addition to these, we can also use the fullmatch() function to get a boolean result from a regular expression. ... Read More

What is QCommerce?Qcommerce combines the rapidity of on-demand delivery with the ease of e-commerce. It includes online platforms that deliver goods—mostly food and other necessities in short time. This concept . Qcommerce uses hidden shopfronts, AI-powered platforms, and other logistics to do this. These help in inventory location and delivery time optimization.How Fast Does Quick Commerce Operates?Quick commerce uses what are known as "dark stores, " which are micro-warehouse models. These are tiny fulfilment facilities that are positioned thoughtfully around crowded cities. By keeping in-demand commodities in these stores, businesses may drastically cut down on delivery times. Q-commerce platforms optimize ... Read More
In this article, we are going to discuss how to use regular expressions in place of a string.replace() method. As you may know, Python's built-in string.replace() method is used to replace given substrings in a string. But when we need more complex replacement features so Python's re (regular expressions) module is very helpful. Regular expressions allow us to search for patterns and replace them with precise values, which makes string manipulation simpler. Why Use Regular Expressions? While string.replace() works well for simple tasks, it has its limitations, like it can only replace exact substrings and has limited ability to use pattern ... Read More
In this article we will be using Regular Expression to get zero or more occurrences within the pattern. Regular expressions (regex) are important features to identify patterns in text. In Python, the re module provides support for working with regex. The concept of zero or more occurrences is a key regex feature. This means that a pattern can appear somewhere between zero and an infinite number of times. Zero or More Occurrences? In regex, the * symbol denotes zero or more instances of the preceding element. For example, the pattern a* will match - ... Read More
Type inference (or, type deduction) refers to the automatic detection of the data type of an expression in a programming language. In C++, the auto keyword is used for automatic type deduction.For example, you want to create an iterator to iterate over a vector, you can simply use auto for that purpose.It is helpful, when dealing with complicated STL containers, iterators, and lambda functions where it may be hard to write the full type. This can be achieved using auto, decltype, and decltype(auto) keywords. These approaches help in letting the compiler understand the correct data types without explicitly declaring them. ...

In Python, recursion is a programming technique where a function calls itself to solve a problem. Backtracking means trying different options one by one and going back if one option doesn’t work. It helps in solving problems step by step, like puzzles or finding the right path. How Recursion and Backtracking Work Together Imagine navigating a maze. We are trying a path, and if it hits a dead-end, we go back and try another. That’s backtracking. The steps of trying and going back are done using recursive function calls. Backtracking frequently uses recursion to explore different possibilities ... Read More
The Copy and Swap Idiom in C++ is a technique used in assignment operations. This consists of two steps: Discarding an object's old state and building a new state for it. The destructor is used for the first step and a copy constructor does the second step. Implementing both of these is straightforward. But when overloading the assignment operator, it can become quite difficult to implement. The copy and swap idiom is a solution for the same. This idiom uses the copy-constructor to build a local copy of the data. It then swaps the old data with the new data ... Read More
Concatenate a string and an integer means, convert both the string and integer to a single string. In this article we will discuss all the approches to concatenate a std:string and an integer type using C/C++ program. First of all, let's understand the problem statement. We are given a standard c++ string and an integer. We have to output a single string by combining the given string and integer. For example: // Input String and Integer "Value = " 25 // Output String "Value = 25" Concatenate String and Int in C++ Here is the list ... Read More
