What does 'clear and unambiguous' mean in relation to algorithm steps?

In relation to algorithm steps, the term 'clear and unambiguous' emphasizes the importance of precision and clarity in the instructions provided. Each action within the algorithm must be exactly described and explicitly stated to ensure that anyone reading or executing the algorithm can understand and perform the actions without confusion. This clarity helps to minimize the chances of errors or misinterpretations that could arise if the steps were vague or left open to personal interpretation. Moreover, a well-defined algorithm allows for consistent execution, meaning that the same set of instructions will yield the same results regardless of who implements them. This prevents discrepancies and enhances the reliability of the algorithm.
