L4 - 1D DP | Climbing Stairs | How Problem Give Hints To Think Recursive? | LeetCode 70 Intuition
Today in Lecture 4, we solve LeetCode 70 (EASY). Climbing Stairs problem using 1D Dynamic Programming and explain how the problem itself gives hints to think recursively. The structure of choosing 1 or 2 steps naturally forms the recurrence that drives the final DP formulation.
