CAOS Guard Duty
Brain Warm-up
In a 5x5unit prison there are 9 inmates and 15 guards. The inmates are numbered 0-8 and the guards are all named G. Your job is to place the guards and inmates in the prison so that only one is in each of the 25 square units (obviously one square unit will be empty). Additionally, each inmate N must be adjacent (horizontally, vertically, or diagonally) to exactly N guards where N is the inmate’s number. Thus, inmate 4 must be adjacent to EXACTLY 4 guards while inmate 0 is adjacent to none.

As a bonus, you can try and do the same task with only 16 guards and no empty space.
