In this article, we introduce array, implementation in different popular languages, its basic operations and commonly seen problems / interview questions. An array stores items (in case of C/C++ and Java Primitive Arrays) or their references (in case of Python, JS, Java Non-Primitive) at contiguous locations.
Arrays provide a structured way to store and access collections of elements, while algorithms for arrays enable efficient manipulation, searching, sorting, and traversal of the data they...
Following are the basic operations supported by an array. Traverse − print all the array elements one by one. Insertion − Adds an element at the given index. Deletion − Deletes an element at the given index.
Discover essential arrayalgorithms and techniques for efficient array manipulation. Learn sorting, searching, rotation, merging, and advanced operations with step-by-step examples and visual explanations.
This article includes links to some of the classic and popular Arrayalgorithms. Boyer-Moore Majority Voting Algorithm The Boyer-Moore Majority Voting Algorithm is a technique used to find the majority element in a given array or sequence of elements in linear time using constant space.
Arrays An array is a data structure used to store multiple elements. Arrays are used by many algorithms. For example, an algorithm can be used to look through an array to find the lowest value, like the animation below shows:
ArrayAlgorithms are defined as functional algorithms where each step of the algorithm results in a function being applied to an array, producing an array result. Arrayalgorithms are compared with non-arrayalgorithms.
We covered Bubble Sort, an algorithms that sorts an array. Say we are given an array called arr, how do we find a specific value, val, in that array? Let’s write a method called linearSearch that will perform a linear search on the array for some value.
The code below rotates array elements to the left. Note that you need to use an indexed loop for this because you need to change the array and access two elements at different indices.
