What are sparse arrays?
Sparse arrays are arrays in which most elements are empty or have default values (like zero), and only a few positions hold meaningful data. They save memory by storing only non-empty elements along with their indices, instead of allocating space for the entire array.

What is tree sort?
Tree sort is a sorting algorithm that builds a binary search tree (BST) from the input elements and then performs an in-order traversal to retrieve them in sorted order.

What is a cyclic sort algorithm?
The cyclic sort algorithm is an efficient, in-place sorting technique used when elements are within a known range, typically 1 to n. It places each number directly in its correct index by swapping, achieving linear time complexity O(n) without extra space.

Array operations in Python
Array operations in Python allow you to store and manipulate collections of data efficiently, such as accessing, inserting, updating, or deleting elements. With libraries like NumPy, you can also perform advanced operations like slicing, mathematical computations, and reshaping arrays.

What is a 3-D array?
A 3-D array is a data structure that stores elements in three dimensions—rows, columns, and depth—like a cube of data. It’s commonly used to represent complex structures such as 3D graphics, matrices, or real-world models.

What is a bigram language model?
A bigram language model is a type of statistical model that predicts the probability of a word based on the word that comes immediately before it. It simplifies language processing by considering only pairs of consecutive words, making computations faster but less context-aware.

What is a hash map in C++?
A hash map in C++ is a data structure that stores key-value pairs, allowing fast retrieval of values based on unique keys. It uses a hashing function to map keys to specific memory locations, enabling efficient insertions, lookups, and deletions.
