Summary

A computer_scientist studies computation and builds reliable software solutions using algorithms and data_structures. They design, write, test, and debug programs in common programming_languages such as Python, Java, and C++. Core ideas include computational_thinking, problem_solving, and abstraction, supported by complexity analysis and big_o_notation. Foundational models like the turing_machine guide theory. Work spans software_engineering, artificial_intelligence, machine_learning, databases, and systems, using testing, version_control with git, and careful system_design. Strong math skills such as discrete_math matter, along with collaboration and ethics.
