The number of different ways to climb a ladder of N steps by taking 1 or 2 steps at a time.

• This is a classic problem that can be solved using dynamic programming.

• The number of ways to climb N steps is equal to the sum of the number of ways to climb N-1 steps and N-2 steps.

• The base cases are when N is 0 or 1, where there is only 1 way to climb the ladder.

• For example, for N=4, there are 5 different ways: [1, 1, 1, 1], [1, 1, 2], [1, 2, 1], [2, 1, 1], [2, 2].
