Cách sử dụng
Permutation refers to the different ways in which a set of things can be arranged or ordered. For example, if you have three numbers, 1, 2, and 3, there are six possible permutations: 123, 132, 213, 231, 312, and 321. This term is often used in mathematics and computer science to calculate and analyze these different arrangements. It can also be used in everyday language when talking about choices or options, such as considering the permutations of different travel plans or job opportunities.
