Question
Rotate the pipe tiles (marked with labels) so that water flows continuously from the SOURCE tile to the SINK tile. For each tile that needs rotating, write: tile label, direction (CW = clockwise, CCW = counter-clockwise), and degrees.
TileTypes
  • {"type":"straight","description":"Straight (\u2500)"}
  • {"type":"elbow","description":"Elbow (\u2514)"}
  • {"type":"T","description":"T-shape (\u252c)"}
  • {"type":"cross","description":"Cross (+)"}
  • {"type":"end","description":"End cap (\u2574)"}
Hint
Work outward from both ends (SOURCE and SINK) simultaneously to meet in the middle.
