what is the relation between data structure and algorithm?

Algorithm is the way to do something with the data in the most efficient way, so as most answers here indicate - Data structures help algorithms achieve their goals in the most efficient way. Data structures are the way to arrange data so that some kind of operations on them get facilitated.

Arrays in Python. One of the most fundamental data structures in any language is the array. Python doesn't have a native array data structure, but it has the list which is much more general and can be used as a multidimensional array quite easily.

Data structure is a process through which data is stored and arranged in the disk space of the computer or memory storage, in a way that the data can be easily used and manipulated in the future. It is an effective way of performing various operations related to data management.

An algorithm is merely the sequence of steps taken to solve a problem. ... Pseudocode is an artificial and informal language that helps programmers develop algorithms. Pseudocode is a "text-based" detail (algorithmic) design tool. The rules of Pseudocode are reasonably straightforward.

A linked list is a linear data structure, in which the elements are not stored at contiguous memory locations. ... In simple words, a linked list consists of nodes where each node contains a data field and a reference(link) to the next node in the list.

While an algorithm is a method containing finite set of instructions used to solving a problem. ... Heuristic algorithm is an algorithm that is able to produce an acceptable solution to a problem in many practical scenarios, in the fashion of a general heuristic, but for which there is no formal proof of its correctness.

An algorithm is a systematic logical approach used to solve problems in a computer while Pseudocode is the statement in plain English which may be translated later into a programming language (program). An algorithm is the semantic while the pseudo-code is just a syntax of the communication about solving a problem.

In a linear data structure, data elements are arranged in a linear order where each and every elements are attached to its previous and next adjacent. In a non-linear data structure, data elements are attached in hierarchically manner. ... In linear data structure, data elements can be traversed in a single run only.

A graph data structure consists of a finite (and possibly mutable) set of vertices (also called nodes or points), together with a set of unordered pairs of these vertices for an undirected graph or a set of ordered pairs for a directed graph.

When we think of data structures, there are generally four forms: Linear: arrays, lists. Tree: binary, heaps, space partitioning etc. Hash: distributed hash table, hash tree etc.

In computer science, a heap is a specialized tree-based data structure which is essentially an almost complete tree that satisfies the heap property: in a max heap, for any given node C, if P is a parent node of C, then the key (the value) of P is greater than or equal to the key of C.

Basically, an array is a set of similar data objects stored in sequential memory locations under a common heading or a variable name. ... While a linked list is a data structure which contains a sequence of the elements where each element is linked to its next element.

Most algorithms consist of an Initialisation phase in which variables are set up, and a Recursive or Iterative stage which recurses through the graph, usually either as a BFS or a DFS. Another idea in algorithms is that of a Greedy Algorithm. ... In this example of DFS, each vertex v is assigned and index D(v).
