Author: 红葉 (MOMIJI), from China, this question comes from his personal blog.
Shikaku Snake Loop
1. Divide the grid into rectangles with the numbers in the cells.
2. Each rectangle is to contain exactly one number and it's showing the number of cells in the rectangle.
3. The blank area that cannot form a rectangle just forms a closed snake loop with a width of one grid, so it will not touch itself (even diagonally), and it will not appear 2*2.

This is the first time that Momiji has created "Shikaku Snake Loop", so it is a very, very simple puzzle. If you have any different thoughts on the description of the rules, please let me know in time, thanks for any kind of feedback.
Solution code: First, the number of rectangles outside the loop; then, the total area of rectangles outside the loop; finally, the number of rectangles inside the loop in the Row 2,4,6,8.

Solving this was easy, but it took me a while to figure out what the last part of solution code means tbh.
