Hint 2 of 2
For each column build the skyline from the tallest stack visible from behind.
Show solution
Approach: read the skyline from the back (mirror left-right)
- Looking from the back reverses the left-right order of the four columns.
- For each column the visible bar height is the tallest stack in that column.
- The resulting skyline (heights 2, 3, 3, 4 from left to right as seen from behind) matches figure C.
- So Johann sees view C.
