In this article, we will discuss different ways to remove specific characters from a string in python. For example, we have a string, And we want to delete all occurrences of some specific characters from the string. These specific characters are, ‘&’ ‘#’ ‘@’ ‘!’ ‘;’ ‘,’ ‘:’ ‘\” After removing these specific characters from […]

In modern C++ programming, smart pointers provides automatic memory management. Among these smart pointers, shared_ptr is widely used because it takes care of releasing memory when it is no longer needed, thanks to reference counting. However, misusing shared_ptr can lead to issues like memory leaks, especially in complex data structures such as binary trees. Let’s
What is weak_ptr in Modern C++ & why do we need it? Read More »
In modern C++, std::shared_ptr is a smart pointer that manages shared ownership of a dynamically allocated object. It is part of the C++ Standard Library’s memory header. Shared pointers keep track of how many objects own a particular resource and automatically delete the resource when there are no owners left. However, if not used carefully,
