Tile Game

Start by inputting a closed loop of turns “L” and “R” and press the draw button. Your goal is to tile the closed loop with the tiles from the tray on the right such that the weight of every hexagon inside the loop is 1, and the weight of every hexagon outside the loop is 0.

Suggested loops:

• RRRRLLRRLRRRRLLRRLR (0-snake)
• RRRRLLRLRRLRRRRLLRLRRLR (1-snake)
• RRRRLLRLRLRRLRRRRLLRLRLRRLR (2-snake)
• RRRRLLRLRLRLRRLRRRRLLRLRLRLRRLR (3-snake)
• RRRLLLRRRRLRRLRRLR (a C)
• RLRLRLRLRLLRLRLRLRLRLRLLRLRLRLRLRLLRLRLRLRLRLRLLRLRLRLRLRLLRLRLRLRLRLRLL (not a room)
• RLRLRLRRRRLLRRLRLRLLRLRLRRLRLLRRRRLRLRLLLRRLRRLRRRLLLLRLRRRRLLRRLRRLLLRLLR (megaman!)
• LRRLRRLRRLRRLRRLRR (kind of hard!)
• LRRLRRLLRRLRRLLRRLRRLLRRLRRLLRRLRRLLRRLRRL

Input a string of turns "L" and "R": draw

Flip the sign of the last tile clicked: negate
