**Data Structures And Algorithms Notes PDF Download:** Data structure is used to store & organize data. Data structure helps in organizing data in an ordered manner so that it can be used in the future for different reasons. The algorithm is the procedure that provides a set of instructions that should be executed in an orderly manner to get the desired result. Some important algorithms from the side of the data structure are search, sort, insert, update & delete. It is important to learn data structure and algorithms to write computer programs.

The algorithm is not the code; it is only the logic of a problem. An algorithm is considered efficient when it takes less time to execute & less memory. If your goal is to become a software engineer, you must start studying Data structures & algorithms. These two things have become very important in every industry in recent times. In this article, you will find complete details about the Lecture Notes & study materials of data structure & algorithms.
