Climbing stairs problem dynamic programming. com In this video, we solve the famous Climbing Stairs Problem — a top-rated Dynamic Programming (DP) and DSA question frequently asked in coding interviews at FAANG and top tech companies. A person can reach nth stair either from (n-1)th stair or (n-2)th stair. This gives us the following recurrence relation: This is essentially a dynamic programming problem where each position can be reached from either the previous step (by taking 1 step) or from two steps back (by taking 2 steps). Master dynamic programming with our easy Climbing Stairs tutorial. Jul 23, 2025 · We can easily identify the recursive nature of this problem. Thus, for each stair n, we calculate the number of ways to reach the (n-1)th and (n-2)th stairs, and add them to get the total number of ways to reach the nth stair.
