Puzzle: a bug is sitting in a bottom corner of a square room. He has to walk to the farthest corner. Which path should it take to pick the shortest possible path?
Note: Don't forget to visit us again. Answer to the puzzle will be posted tomorrow.
Solution: To reach to opposite corner bug has to cross atleast two walls. The shortest distance to cross a wall is if it goes directly towards the midpoint of the edge. This makes an equilateral triangle.
Winner: once again Kasturi is winner. Her explanation is also cool.
If we consider only the two walls between the source and destination corners, and unfold them to form a rectangle, the shortest path between the corners is the diagonal. By that logic, the path that the bug should take is this: he should walk to the midpoint of the adjacent vertical edge and then to the destination corner.
