ahem — at random. OK, so you still have to pick a starting number. To get the next number, take the top digit, add six, and then multiply by the bottom digit. So in C: n1=(n/10+6)*(n%10). Then use the last digit as your random number from 0 to 9. Why does it work?

If random.seed() is not called, the random number generator is seeded with random bits from the system time. This can be predictable.Generate random string with os.urandom()Instead of using the system time as seed, you can use os.urandom() or random.SystemRandom(). It is more ...
In our software, each item has its own 12 digit unique barcode. We are getting close to having 1 million records which out of 500 million, you would think we would not have any problems. I ran a test with our script and generated and logged 990,319 barco

The below function will print anything between 0 and 9. It's the same for all ranges. public static void main(String[] args) { int b = randomNumberRange(0, 9); int d = randomNumberRange (100, 200); System.out.println("value of b is " + b); System.out.println(...
But there’s another thing you might be curious to know: pi, far from being unpatterned, actually follows a very well-defined pattern. You can write a short computer program that will perfectly predict every digit of pi if you wait long enough. In doing so, you compress the information ...
