3. The n×n regions marked with dotted line should fill with n numbers from 1~9, and it should be exactly divided into n parts with n cells like a small jigsaw sudoku.

I really enjoyed this sudoku! Very fun solve :)
I didn't understand how to get the solution code at first, so in case anyone else is also confused:
"all the sudoku" = the grid, plus the three cages.
So R1 / R4C4-7 / R2C2-4 / R7C7-8.
