Hi mekonbekon
Thanks for your reply and it really helped me to understand these words, still there are some points
1) I got understand Threshold complete and no confusion.
2) Now I understand what is Permutation but a little confusion
For example a length of 3 with an offset of 1 will generate the numbers 1, 2 and 3, and then randomly shuffle them.
according to above line I understand that offset of 2 will generate the number 1,2 and 3 and then again 1,2 and 3 and after this randomly shuffle. I mean if offset is 1 then there will no randomness for the first time and if offset will be 2 then there will No randomness for 2 times and then after than random will start. Am i right ?
3) From your explanation about seed i understand that if seed will be 0 then each time random sequence will be different but if seed will be 1 then first random sequence will be repeated for all next sequences. Am I Right?
