The number of on-demand computers has important applications in many fields, such as Monte Carlo simulation, cryptography, and network security. The random number quality is directly related to the reliability and security of the network security system, and to the reliability of the Monte Carlo simulation results.

For more information, see numerical recipes in C ++ 2/e p.292 ~ P.294 and Simulation Modeling and Analysis 3/e p.465 ~ P.466. Box and Muller provided an algorithm for generating a normally distributed random variable from a uniformly distributed random variable in 1958. Where U1 and U2 are random variables with a uniform distribution on the intervals (0, 1), they

in 0 and mod-1 of all numbers, then it will evenly generate pseudo-random numbers with each mod iteration. If the step= 15 and mod = -, the function generates series 0, the,Ten,5(or any other repeating series if the initial seed is not 0). This is a poor step and mod selection because no initial seed will be generated from 0 and mod-1 of all numbers. Your program will determine whether the selection of step and mod will generate a uniform distributio
