A basic program has three steps; an input, a process and an output. To make the program fast and efficient, it needs to be optimized. This is where Data structures and Algorithms pitch in. Data structures stores the data in a structured format so that it can be easily processed and displayed. Algorithms on the other hand help in reducing memory space and process the data swiftly. As the program complexity increases, Data structures and algorithms become very crucial in improving the performance of the program.
