Sorting is an arrangement of data in a particular order. an algorithm can be implemented in more than one programming language. But if we talk about sorting in Data Structure then it's more relevant to rearrange the data or element in ascending or descending order which can be lexicographical, numerical, or maybe user-defined. Step 2: If it is a match, return the index of the item, and exit. Data Structures is about rendering data elements in terms of some relationship, for better organization and storage. Data structures are Computer and IT MCQs. An algorithm is defined as a step-by-step procedure or method for solving a problem by a computer in a finite number of steps. 5.
