In this video, we solve LeetCode 12 – Integer to Roman, a classic greedy + mapping problem from the LeetCode Top Interview 150 series.
We walk through:
1. How Roman numeral rules actually work (including subtractive cases like IV, IX, XL, CM)
2. Why a greedy descending-value strategy is the cleanest solution
3. Writing clean, interview-ready C++ code using constant space
4. Avoiding common pitfalls and overcomplicated logic
This problem is frequently asked in FAANG interviews and tests your ability to translate real-world rules into deterministic code.
