    Random Number Generation

    From ancient times when coins were flipped and dice rolled for gambling, people have needed random number generation. Formally defined, a random number generator is a physical or computational device which generates an array of symbols or numbers with no pattern. There has always been a large demand for random data generation from everything requiring unpredictable results, from the lottery, to computer simulations to cryptography to statistical sampling. There are two main methods of generating random numbers:

    • physically

    Physically-based random number generators take advantage of naturally-occurring randomization. True examples of these are difficult to find, but the most commonly-used ones are atomic or subatomic phenomena such as radioactive decay, whose randomness is guaranteed as a result of the laws of quantum mechanics. It is necessary with this method to ensure you are compensating for any biases that may occur as a result of measuring this random natural process, however.

    • computationally

    This method makes use of algorithms designed to produce unpredictable results by performing operations on a 'seed' key that is given as input. They are often complex, but also known as 'pseudo-random number generators' as there is a relation between the values and the seed, however distant.

    As well as produce random numbers, there exists a type of tool called a randomness extractor which turns randomly-arranged data into a uniform distribution. A cryptography hash function is a good example of such a tool.

    Guessing Game

    Write a program in C++ to play a guessing game with the user. The program should be able to make a guess about the chosen number by the user and ask whether the guessed number is above or below the chosen number. If the guess is correct the program should report the number of tries and the correctly guessed number. As an advanc

    Java - Permutation Programs

    Write a program that produces random permutations of the numbers 1 to 10. To generate a random permutation, you need to fill an array with the numbers 1 to 10 so that no two entries of the array have the same contents. You could do it by brute force, by calling Random.nextInt until it produces a value that is not yet in the arra
