Recursion breaks the problem into smaller ones and is easier to use. In recursion, the same operation is performed multiple times with the smaller inputs to make the problem smaller
The analysis of algorithms is to find the complexity of algorithms in terms of time and storage. In theoretical analysis, the analysis is performed based on the description of the algorithm, or the operation of the program or function
Data Structure is a systematic way of organizing the data on the computer. Data is nothing but some useful information like documents, photos, videos, audio, or programs stored in computer memory.
