WebbPractice this problem. Let T(n) be the total number of ways to reach the n'th stair from the bottom. Since a person is only allowed to climb either 1 or 2 or 3 stairs at a time, we can reach the n'th stair from either (n-1)'th stair, (n-2)'th stair, or from (n-3)'th stair. Considering this, the recurrence relation T(n) can be written as: fancy soda brandsWebbDP - Top-Down Approach - Recursion with memorization.
