This article explains the concept of isomorphism in graph data structures. A pair of given graphs are said to be isomorphic graphs if they are structurally equivalent. It means there exists a mapping(bijection) between the vertices of the two graphs. Using this mapping, one graph can be converted into the other by replacing its vertices ...
Problem Statement You are given a set of N jobs, where each job is having a deadline and a profit associated with it. You can only earn a profit if you complete the job within its given deadline. You can perform the job either before the deadline or strictly on the deadline, not after that. Rules: Input Format: The jobs will be ...
The common prefix between the two most dissimilar strings is the longest common prefix for an array of strings. For instance, there is no common prefix in the array apple, ape, and zebra since the two most distinct strings in the array, “ape” and “zebra,” do not share any initial letters. In this article, we will learn about the ...
Sort a stack involves the task of arranging the elements within a stack in a specific order, either ascending or descending, using only a limited set of stack operations like push, pop, and peek. The goal is to achieve this sorting without utilizing extra data structures, such as arrays or lists. The challenge lies in ...
When you want to send files or store the files on a computer, if the size is very huge we generally compress it and store it. One way of compressing these files is using Huffman Coding which is a greedy-based algorithm that is also known as variable-length coding or lossless data compression technique. Introduction to ...
The set of instructions is repeated using both recursion and iteration. When a statement within a function repeatedly invokes itself, recursion occurs. Iteration happens when a loop runs repeatedly until the controlling condition is satisfied. Recursion and iteration vary fundamentally doing the same thing. iteration is used to apply a set of instructions that we want ...
Data Structures and algorithms is one of the most important topics that you need to have knowledge of along the path of being a software developer. The knowledge of this topic helps solve problems much more easily in the real world. It’s a skill that comes with practice. In this article, I will speak about the best ...
An array is a linear collection of values stored at contiguous memory locations. A subarray is nothing but a slice of these contiguous memory locations of the actual array or we can say that a subarray is nothing but any contiguous part of a given array. A subset is often confused with subarray and subsequence ...
A tree is a nonlinear hierarchical data structure that consists of nodes connected by edges. The most common type of tree is the binary tree. In this, each node has 2 children, i.e., Left and Right. The node that doesn’t have any parents is known as the root node, and the node that doesn’t have any children nodes is known as the leaf node. ...
A linked list can be considered as a train, where each boogie is connected by links. Formally defined, a linked list is a linear data structure that consists of nodes that are connected. Each node has some data associated with it, along with the address of the next node. The last node of a linked list points ...
