"WebDec 16, 2024 · While generating permutations, let’s say we are at index = 0, and swap it with all elements after it. When we reach i=2, we see that in the string s [index…i-1], there was an index that is equal to s [i]. Thus, swapping it will produce repeated permutations. Thus, we don’t swap it. The below explains it better. " - Binary permutations

It would be great if it would be roughly efficient since I'll have to do that with a list of even 30 elements like this. WebThis technique does generate permutations where an item is used more than once, which is useful for generating 3-operator possibilities from the provided collection of 5 operators (e.g. ( ( ++′, ′ + 1,′+1),(1+ 1,′+1,′ −1),…) when k = 3).

The generalization to radix representations, for , and to , is a digit-reversal permutation, in which the base- digits of the index of each element are reversed to obtain the permuted index. The same idea can also been generalized to mixed radix number systems. In such cases, the digit-reversal permutation should simultaneously reverses the digits of each item and the bases of the number system, so that each reversed digit remains within the range defined by its base.
