I want to generate a pseudo random number sequence which doesn't repeat any of its elements.
For example,I need 25 elements in that sequence,the values of elements ranges from 1 to 25,and no elements should be repeated.(Actually,the number of elements i need in that sequence is very large).
Also,this sequence should be reconstructable (using a seed) later.
How can i do that?I read about randperm. But i think its not suitable in this case.
