In the tower of hanoi problem, the state involves having three discs stacked on the left peg, with the middle and right pegs empty.

The tower of Hanoi problem is a mathematical problem, invented by the French mathematician Edouard Lucas in 1883. The initial state involves having three discs stacked on the left peg, with the middle and right pegs empty.
