Swift Enum (Enumerations) by Example - Swift Programming Language An enumeration defines a common type for a group of related values and enables you to work with those values in a type-safe way within your code. Types of Enumeration: * Basic Enumerations * Enumerations with Raw Values * Enumerations with Associated Values 1. Basic Enumerations 1.1 Create an enumerations * To create...

Data Structure Introduction to Greedy Algorithms 1. What is Greedy Algorithm? A greedy algorithm, as the name suggests, always makes the choice that seems to be the best at that moment. This means that it makes a locally-optimal choice in the hope that this choice will lead to a globally-optimal solution. However, generally greedy algorithms do...
Data Structure Introduction to Divide and Conquer (D&C) Algorithm Design Paradigm 1. What is Divide and Conquer? Divide and conquer (D&C) is an algorithm design paradigm based on multi-branched recursion. A divide and conquer algorithm works by recursively breaking down a problem into two or more sub-problems of the same type, until these become simple enough to be solved...
Data Structure Introduction to Asymptotic Notations 1. What is Asymptotic Notations? Asymptotic Notations are languages that allow us to analyze an algorithm’s run-time performance. Asymptotic Notations identify running time by algorithm behavior as the input size for the algorithm increases. This is also known as an algorithm’s growth rate. Usually, the time required by...
Data Structure Introduction to Data Structures and Algorithms 1. What is Data Structure? A data structure is a particular way of organizing data in a computer so that it can be used efficiently. Data Structures is about rendering data elements in terms of some relationship, for better organization and storage. For example, we have data of an employee...
