help with random combination from lists

[maher123us]

hey! i need help with this.

lets say i have 2 lists [A,B,C] nd [1,2,3]

how can i generate all the 9 unique combinations in a random way?

that is--as an example


once B1 is generated it shouldnt generate B1 again..and after generating all 9 combinations randomly it will stop.

You count the number of pairs you can get.
You loop on the number of pairs already done.
At each step you repeat a random choice of elements of L1 and L2 until the pair [C1, C2] is not already found.
(sorry for my bad English).

Antother possibility : you get all the combinations possibles and then shuffle the list.
