492. Pathway with 7 matchsticks

Easy Medium Hard Extreme


7 matchsticks are used to form a pathway as shown above. The challenge is to start at a point, move in the direction of the matchstick heads and visit each of the 7 matchsticks only once.

A solution is not possible in the existing figure above, but by changing the direction of 3 matchsticks it can be achieved. How would you do this?
