Guess and Check, Work Backward
Guess and Check and Work Backward are problem-solving strategies employed across various disciplines, from mathematics to computer science. Guess and Check involves making educated guesses and refining them through trial and error until a solution is found. Conversely, Work Backward requires starting from the desired outcome and working in reverse, breaking down the problem into manageable steps. These methods are invaluable tools for tackling complex problems efficiently and effectively, allowing individuals to approach challenges with a structured and systematic approach, ultimately leading to successful resolutions.
