What is the difference between an algorithm and a program, and how do they each contribute to the process of solving computational problems?

An algorithm is a step-by-step procedure for solving a problem, while a program is a set of instructions written in a specific programming language to implement the algorithm on a computer. Algorithms provide the logic and structure for solving computational problems, while programs execute the algorithm to produce the desired output. In essence, algorithms define the problem-solving approach, while programs implement that approach to find solutions.
