Random vector non repeated otherwise create new vector
1 ビュー (過去 30 日間)
I have number list from 1 to 5. We know there are 120 different permutation for these. I want to write a rule that for my algorithm, I want to create a permutation that does not creaated before. For example,
1 2 3 4 5 first
2 3 4 5 1 second
2 3 4 5 1 nth it shouldn't be created. It is already in the second iteration.
So, by this manner creations should end at most 120th trial.
Can you help me solve this? I'm using randperm
