Written on 11:38 pm by Vja Students
Consider a chessboard with a single Rook.A Rook can move any number of square sideways/forward,but not diagonally.What is the minimum number of moves the Rook needs to make in order to pass over all the squares on the chessboard and return to the original position?
Answer
16 moves
hey we can move it in 15 moves!!!
the bottommost horizontal line first and then to the next above horizontal line..this can be in 2 steps...after 14 steps similarly we complete 56+1 lines. the last 7 can be swept off in the 15th step
