Explanation:
1. Place the 1 on the first middle row, then go right and then go down and place a 2. After that, go right
and up and place a 3. Do that until there are no box left on the right side of the number. When there is
no number left then you go a box up and go all the way left and do the same thing again with the right
and up until you reach 1. To place the 10 go one box below 10 and do the same thing (right and up). Do
that until you reach 77. When you reach there instead of placing the number in the bottom you place it
on the top.
