- Data structures provide a means of managing large amounts of data, enabling efficient searching, sorting, insertion, and deletion of data.- The choice of data structure for a particular task depends on the type and amount of data to be processed, the operations that need to be performed on the data, and the efficiency requirements of the program. - Efficient use of data structures can greatly improve the performance of a program, making it faster and more memory-efficient.- The idea is to reduce the space and time complexities of different tasks. - The choice of a good data structure makes it possible to perform a variety of critical operations effectively. - An efficient data structure also uses minimum memory space and execution time to process the structure.
