WebbSo to optimize this solution we use Dynamic Programming. In the Dynamic Programming solution, we consider that we are standing at the ith step. Then the number of ways to reach ith step is from i-1 step, i-2 step, or i-3 step. So formally speaking, ways [i] = ways [i-1] + ways [i-2] + ways [i-3], using this recursive formula.
