What is a data structure?

A data structure is a specific way of organizing and storing data in a computer so that it can be accessed and manipulated efficiently.

What is an algorithm?

An algorithm is a set of steps designed to solve a problem or perform a specific task.

What is an array?

An array is a collection of elements of the same data type stored in contiguous memory locations.

What is a linked list?

A linked list is a collection of nodes, where each node contains a value and a pointer to the next node in the collection.

What is a binary tree?

A binary tree is a tree structure in which each node has at most two children, which are referred to as the left child and the right child.

What is a stack?

A stack is a data structure that stores a collection of elements, with two main operations: push, which adds an element to the top of the stack, and pop, which removes the element from the top of the stack.

What is a queue?

A queue is a data structure that stores a collection of elements, with two main operations: enqueue, which adds an element to the back of the queue, and dequeue, which removes the element from the front of the queue.

What is a hash table?

A hash table is a data structure that stores a collection of key-value pairs in a way that allows for efficient insertion, deletion, and lookup operations.

What is a sorting algorithm?

A sorting algorithm is an algorithm that puts elements of a list in a certain order, such as ascending or descending.

What is a searching algorithm?

A searching algorithm is an algorithm that finds the location of a desired element in a list or data structure.

What is recursion?

Recursion is a technique in programming where a function calls itself to solve a problem.

What is dynamic programming?

Dynamic programming is a technique in programming where a problem is broken down into smaller subproblems that are easier to solve, and the solutions to those subproblems are combined to solve the original problem.

What is a graph?

A graph is a data structure that consists of vertices/nodes and edges/links that connect them.

What is a heap?

A heap is a data structure that stores a collection of elements and always keeps the largest or smallest element at the top.

What is time complexity?

Time complexity is a measure of the amount of time required to run an algorithm as a function of the size of its input.
