Teacher-given code analysis

Solution:

1. The code given by the teacher is written in C # language, according to my understanding and analysis with roommates we feel that this code is to find the number of the 30 numbers that satisfy 2 to 31 of the 28 number of common multiple and this number can not be divisible by the remaining 2 numbers (these two numbers are continuous). And this number is between 1 and 2 of the 64-time-square.

2. I think this number does not exist, because the number given is a continuous number, so the number to meet this requirement must be two consecutive primes, and the successive primes only 2 and 3, so this number does not exist.

3. I can't figure it out, no time.

4. Increase the frequency of the CPU, improve the algorithm, and replace a solid-state drive.
