If we look at the permutation meaning, it is a process of selection in which all cares about the order. In other words, a permutation is a number of ways in which a few or all members are arranged in a particular order. For example, arrangements of digits, alphabets, and numbers properly. A permutation is divided into two different types. The first one is the “Permutation with Repetition”, which means if there is no possibility for the first selection process, then there will be no possibility for the second selection and so on. The second type is “Permutation without repetition”; in this type of permutation, no repetition and order matters.
