Dear steemit !
lets start game !
At dark night with no moon light.
If there is 4 persons with 1 flash light crossing bridge , which is not well . But condition is that at a time only 2 person pass the bridge with flash light . And total time is 17 mints.
P1 take 1 mint for crossing bridge ,P2 take 2 mints ,P3 take 5 mints , P4 take 10 mints
So task is how these 4 person cross the bridge in 17 mints.
Let's me know what's in your mind in comment .
