This one is a basic linked list problem. Here is the problem link. See the detailed explanation there. This problem is very simple and straightforward. We have to delete the given node. We don’t need to check anything and don’t need to return anything. See the note in the below of the problem explanation. Suppose

This problem is all about designing a stack data structure. Here is the problem link. See the detailed explanation there. To solve this problem, we have to write the most common stack operations. A stack is an abstract data structure. It’s Follow the LIFO (Last In First Out) rules. I hope you already know about
It’s a classic programming problem and a very beginner type of problem. Here is the link to the problem. See the explanation in LeetCode first. And try to understand the problem. First, we will be given a number n as input. We have to store each number from 1 to n in an array as
Here is the link to the problem. See the full explanation on LeetCode first. Try to understand the problem. It’s an easy problem. So the problem is, we have to return the length of the last word from the given string. The string can be consist of uppercase and lowercase letters and separated by a
LeetCode is one of the most popular websites for practicing programming problems. It has a large collection of programming problems to solve. It also helps you to upgrade problem-solving skills one step further. I just love this website. I am going to start writing LeetCode’s solution on my site to improve my depth of understanding
There are lots of programming languages. From those languages, I have some favorite languages. Python is one of them. I use Python on problem-solving sites mostly. Python is a general-purpose programing language. And it is created by the Dutch computer programmer Guido van Rossum. The first release was in 1991. Python has one of the
The stack is a data structure. To implement a stack data structure, we can use both linked list or array. Below are examples of both types of implementation. Using Linked List Using Python List

We can see linked list implementation in python in the following code. And with some important operations of the linked list. The time complexity of every operation is O(n) except insert_front and empty. And the complexity of insert_front and empty is O(1). Singly Linked List Doubly Linked List
Linear Search is the easiest Search algorithm in computer science. If you ever try to search an element in a list sequentially, you already used a linear search algorithm. Congrats! You know already. You may learn more details about the linear search by reading this article. It’s also known as sequential search and simple search.
