Suppose a watch man is sitting at the middle of a bridge and you must cross the bridge. The good thing is that the watchman always sleeps but the bad thing is he automatically wakes as soon as you reach the middle of the bridge and sees that you are crossing the bridge and sends you back. How will you cross the bridge?

- when i reach the middle of the bridge and the watchman catches me i'll tell him that i came from the other end of the bridge(ie. the end of the bridge i started from) or turn back towards the end of the bridge i started from.so the watchman will send me to that side of the bridge where i have to go.

- After reaching the middle of the bridge, when i see that the watchman is about to wake up, i'll just turn 180 degree. they will think that i have just crossed the middle of the bridge, and he can't allow this. He will ask me to go back to the back side ( here it is the side i am approaching). And this way i will cross the bridge.. :)

- as watchman was sleepin when i crossed half way. so when he'll wake up i'll say him that i came from other way ( the way where i want to reach), & he'll send me there.thus, bridge crossed.
