A climber faces a staircase with n steps. Each move climbs one step or two steps. Count the different ways to reach the top, where two ways are different if the sequence of moves differs. Use a table of ways for each number of steps, and remember that the count can be large, so use long.
Input. One line with one integer `n`, where 1 <= n <= 45.
Output. One integer: the number of ways to climb exactly `n` steps.
