. There is no adjacent primes. Problem Solving Ideas: First of all, unlike ordinary prime number screening, because the upper limit of u is very large, only one time from 2-2147483647 of the filter will definitely time out, and do not work, unless the improved algorithm, otherwise you need to change ideas. Then, you can consider only the
