Longest Palindromic Substring refers to finding the longest contiguous substring in a given string that is a palindrome, which is a sequence of characters that reads the same backward as forward. For example, in the string “babad”, the longest palindromic substring is “bab”, which is a palindrome because it reads the same backward as forward. […]

Read MoreThe Container With Most Water is a classic problem in algorithmic and computational thinking, that is often used to test the efficiency and problem-solving skills of developers. The problem statement is as follows: You are given a list of n non-negative integers, where each integer represents a vertical line at position i with a height […]

Read MoreThe problem we’re looking at is called “Median of Two Sorted Arrays.” Essentially, we’re given two sorted arrays of integers, and we need to find the median of the combined array (i.e., the middle value when the two arrays are merged together). The twist is that we’re not allowed to actually merge the two arrays […]

Read MoreThe problem “Longest Substring Without Repeating Characters” is a classic algorithmic problem in computer science. Given a string, the task is to find the length of the longest substring within the string that does not contain any repeated characters. For example, consider the input string “abcabcbb”. The longest substring without repeating characters is “abc”, which […]

Read MoreA tree is a data structure used in computer science to represent hierarchical relationships between objects. It consists of nodes (or elements) connected by edges, which define the relationships between them. Each node can have zero, one, or multiple child nodes, and the connections between the nodes are referred to as branches. Trees are useful […]

Read MoreThe problem of finding the nth node from the end of a linked list involves finding the node that is n positions away from the end of the linked list. For example, if the linked list has 10 nodes and n is 3, we need to find the 3rd node from the end of the […]

Read MoreA palindrome is a sequence of characters that is read the same forward and backward. For example, “racecar” is a palindrome. In the context of a linked list, we can consider it a palindrome if the sequence of values in the list is the same when read from left to right and from right to […]

Read MoreA linked list is a data structure in which each element in the list, known as a node, contains a value and a reference to the next node in the list. Here’s an example of a linked list: In this list, each node contains a value and a reference to the next node in the […]

Read MoreIn software development, code review is a critical process that helps to improve code quality, reduce errors, and maintain consistency across the codebase. With the growing complexity of modern software systems, reviewing code manually can be a time-consuming and error-prone task. Fortunately, there are several tools available that can automate the code review process and […]

Read MoreData structures are an essential part of computer science, and they play a critical role in designing efficient algorithms. Two of the most commonly used data structures are arrays and linked lists. While both of these data structures are used to store and manipulate collections of data, they differ in their implementation and functionality. In […]
