Here I try to solve the problem from the web https://projecteuler.net/
And for now 2022/5/31, I have solved the problems range 1 to 15 and then 18. While problem 16 indeed freezes me out for a long time and the problem 18 was finished at least one year before. In the next time, I will spend more time on thinking of them and log here for showing my coding skills` upgoing out.
