1D Arrays:Usage: 1D arrays, also known as vectors, are used to store and manipulate a collection of data points in a single dimension.2D Arrays:Usage: 2D arrays, also known as matrices, are used to represent data in a two-dimensional grid format with rows and columns.Multidimensional (nD) Arrays:Usage: Multidimensional arrays extend the concept to more than two dimensions, allowing for the representation of complex data structures.

In data science, arrays are fundamental data structures used to store and manipulate data. They are used to represent and work with multi-dimensional data, such as numerical values, images, time series, and more. The three most common types of arrays used in data science are 1D (one-dimensional), 2D (two-dimensional), and 3D (three-dimensional) arrays.

3D Arrays:Definition: A 3D array is an extension of the 2D array, where elements are arranged in a three-dimensional structure with multiple layers.
Usage in Data Science:
Representing volumetric data, such as medical imaging data (e.g., MRI or CT scans).
Storing time series data with multiple variables, such as sensor data with measurements over time for different sensors.
Representing video data, where each element represents a pixel value at a specific time frame.
These array structures are used extensively in data preprocessing, feature engineering, model training, and model evaluation in various data science tasks, including machine learning, image processing, signal processing, and more. The choice of array type depends on the nature and requirements of the data being analyzed or processed.

2D Arrays:Definition: A 2D array, also known as a matrix or a two-dimensional table, is a collection of elements arranged in a grid-like structure with rows and columns.
Usage in Data Science:
Storing tabular data, such as datasets in a spreadsheet-like format.
Representing images, where each element represents a pixel value.
Working with mathematical operations that involve matrices, such as linear algebra and matrix factorization.

1D Arrays:Definition: A 1D array, also known as a vector or a one-dimensional sequence, is a collection of elements arranged in a linear manner.
Usage in Data Science:
Representing a series of data points, such as stock prices over time.
Storing feature vectors in machine learning algorithms, where each element represents a feature.
Representing time series data, such as temperature measurements over time.

Why we have 1D, 2D and 3D arrays and where we need them in data science?
