You can put this solution on YOUR website!
Some website rules you won't like:
You are limited to one problem per submission. [One problem at a time.]
To be sure we understand each other, one means one not two or three or more.
No more than 4 submissions daily. [4 problems a day]
No similar problems. [Different type problems only.]
There are no answers today because you didn't follow the rules and so you can't put it in the right category. Each problem needs its own category.
