non repeating random number generator

Header file Now I want to generate a random number, I use the following program:#include The problem comes, although we produce a random number, but no matter how many times I run the above program (recompile, run, also 41), it produces a definite number. That is, 41, as fol

Recently saw an interview with Baidu: How to find the number of non-repeating numbers from 250 million integers Write the following implementation, the time is slightly tight, the idea is slightly coarse, there are errors also please point out. Thank you. int[] isrepeat = new Int[arr.length]; modified to int[] Isrepeat = new int[250000000]; Need to request the JV

DescriptionGiven the number of n, it is required to remove the duplicate, only the first occurrence of the number. For example, the number given is 1 2 18 3 3 19 2 3 6 5 4, of which 2 and 3 have duplicates, the result of removal is 1 2 18 3 19 6 5 4.InputEnter the first behavior positive integer t, which indicates that there is a T group of data. Next, each set o

Recent lab projects need to implement a simulated file access sequence that requires the number of data requests per unit time to be in accordance with the Poisson distribution, while the time interval of two requests meets the exponential distribution. There is no way to re-pick up the probability that has been lost a long knowledge. Then there is the implementation of the random

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
