FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Answer. Explanation: The order in the algorithm matters since it is used as a rough idea for the original program. If the order is messed you might get an error or a wrong output in the program.

Detailed explanation-2: -It’s about writing a list of instructions to tell the computer what to do step by step. In an imperative programming paradigm, the order of the steps is crucial, because a given step will have different consequences depending on the current values of variables when the step is executed.

Detailed explanation-3: -When the order doesn’t matter, it is a Combination. When the order does matter it is a Permutation.

Detailed explanation-4: -With permutations, the order of the arrangement matters. There are three different types of permutations, including one without repetition and one with repetition. Permutations are different from combinations, where data is chosen from a group and the order doesn’t matter.

Detailed explanation-5: -“Order matters” means that re-arrangements of numbers (-feel free to consider these numbers to be “items” or “events”, if appropriate-) are considered different. For example (1, 2, 3) is one arrangement, and (1, 3, 2) is a different arrangement of the numbers 1, 2, and 3.
