📝 Walkthrough

Walkthrough

A new LeetCode solution for the "Climbing Stairs" problem is added with dynamic programming implementation, along with corresponding parameterized test coverage to validate the solution against multiple test cases.

Changes

Cohort / File(s)	Summary
LeetCode Solution Implementation LeetCode/easy/climbing_stairs_70.py	Introduces a Solution class with climbStairs(n: int) method implementing Fibonacci-like dynamic programming using two rolling variables to compute distinct ways to climb n stairs.
Test Coverage tests/test_leetcode_easy.py	Adds parameterized test function test_climb_stairs with multiple test cases covering base cases (n=1, n=2), Fibonacci-like sequence, and larger input (n=10).

Poem

🐰 A staircase so fine, step by step up we climb,
With two rolling hops, we keep perfect time,
Each step counts the ways, like Fibonacci's song,
The stairs celebrate—our logic is strong! 🥕✨
