Deloitte Computer Science Quiz-4

Explanation:
Data structures are methods used to organize and store data in a computer system, allowing efficient access and modification of information.

Explanation:
In data structures, an array is a method of storing similar data elements, enabling easy access and manipulation of these elements.

Explanation:
The main advantage of a linked list over an array is its flexible size and efficient insertion and deletion capabilities, making it more adaptable for data manipulation.

Explanation:
A stack in data structures represents a collection of elements with Last In, First Out (LIFO) access, enabling addition and removal of elements from the top.

Explanation:
The principal characteristic of a queue in data structures is its First In, First Out (FIFO) access, allowing elements to be added at the end and removed from the front.

Explanation:
In data structures, a binary tree is a tree-like structure with a maximum of two children for each node, facilitating efficient data organization and retrieval.

Explanation:
A hash table in data structures enables direct access to data through key-value pairs, facilitating efficient data retrieval and storage.

Explanation:
A graph in data structures primarily represents hierarchical relationships between data elements, aiding in the visualization and comprehension of complex connections.

Explanation:
The main purpose of a heap in data structures is to efficiently maintain the maximum or minimum element, allowing quick access to extreme values within a dataset.

Explanation:
A trie in data structures is primarily characterized by its efficient search and retrieval capabilities for data with common prefixes, making it suitable for applications such as autocomplete and spell checkers.
