👉 An array fluid, also known as an array of arrays or a multi-dimensional array, is a data structure that organizes elements into multiple, independent one-dimensional arrays, each of which can hold a different type of data. This structure allows for efficient storage and manipulation of complex data sets by enabling operations on each sub-array individually, while still benefiting from the compact and flexible nature of arrays. Array fluids are particularly useful in scenarios where data needs to be accessed or modified in a structured, yet adaptable manner, such as in machine learning algorithms, scientific computing, and data analysis applications. They provide a balance between the simplicity of one-dimensional arrays and the complexity of multidimensional arrays, making them versatile tools in programming.
