Study Notes
Computer Science
Computer science is the study of computers, computer systems, and computational methods. It encompasses a wide range of subdisciplines and topics, including algorithms and data structures.
Algorithms
An algorithm is a set of instructions that a computer programmed to solve a specific problem. There are several types of algorithms:
-
Recursive Algorithms: These algorithms call themselves, aided by a base case to stop the recursion when the problem has been solved.
-
Greedy Algorithms: These algorithms work by making the locally optimal choice at each stage with the hopes of finding the globally optimal solution.
-
Dynamic Programming Algorithms: These algorithms break down a complex problem into simpler sub-problems and solve each sub-problem only once.
-
Backtracking Algorithms: These algorithms generate all possible solutions to a problem, then prune the ones that do not satisfy some constraint.
Data Structures
Data structures refer to specialized formats for organizing and storing data so that they can be accessed efficiently and in a logical manner. Some common data structures include:
-
Arrays: A collection of items stored at contiguous memory locations, accessed by their index or key.
-
Linked List: A linear collection of elements with each element pointing to the next one in the sequence.
-
Stack: A last-in-first-out (LIFO) data structure where the most recently added element is also the first one to be removed.
-
Queue: A first-in-first-out (FIFO) data structure, similar to a queue of people waiting for service.
-
Tree: A hierarchical data structure that models a set of pairwise relations between objects called nodes.
Conclusion
Computer science involves algorithms, which are sets of instructions that solve specific problems, and data structures, specialized formats for organizing and storing data. Understanding these concepts is crucial for effective programming and problem solving.
