I'm a novice My task is to create a script a that examines a list of numbers (for example, 2, 8, 64, 16, 32 4, 16, 8) to determine whether it contains duplicates. I want to generate 36 random numbers from 1 to 36 without having any duplicate numbers in the sequence. randint (1,21)* 5, print. All computer-generated random sequences will hit dups sooner or later. For now with my formulas, I am able to auto shuffle the number for Col M and N based on what I have insert on column A which is 20. Sets the seed of this random number generator using a single long seed. [code]static void Main(string[] args) { var numbers = new List<int>(); var numberOfNumbersYouWant = 4; // This has to be less than 11. This card generator enables you to include random card holder name so you do not need to come up with a name on your own. Random Number Generator.
