Random picking algorithm
Hi.
I'm searching in the internet for information, examples for algorithms, that can randomly pick a value from a define list of values, I found several examples that can do random on a array but thru the index of the array, what I want is: based on the values in each position of the array the algorithm picks a random value in each iteration until there are no values in the array. Example
int[] array = new int[]{4,245,653,9,12,50}
A possible output for this could be
50,4,9,12,653,245
I don't know if I explain my self well enough, thanks for any help, code example, link to pseudocode, or any type of information

Thanks for the reply, I also so that algorithm, and after reading what I have written, I didn't explain the idea correctly, what I want is to put the data randomly in N arrays depending on that N number, example:
int[] array = new int[]{4,245,653,9,12,50}
A possible output for this could be for two arrays
array A : 50,4,9,
array B: 12,653,245
I can use the shuffle to do a double shuffle, one for the picking and another for the attribution to one of the N arrays.
This will do the trick
