Set Matrix Zeroes - Google DeepMind Interview Question Explained | LeetCode 73 | ML Engineer

This exact problem was asked in a Google DeepMind ML Engineer interview — and most candidates fail the in-place O(1) space constraint. Here's the visual explanation of exactly how to solve it. What you'll learn: ✅ Why the naive approach of marking zeroes during traversal corrupts the result ✅ How to use the first row and column as markers (O(1) space trick) ✅ Two-pass strategy: mark → apply ✅ Edge case: when row 0 or column 0 itself contains a zero ✅ Python implementation used in top AI company interviews 🎯 Real Google DeepMind ML interview question — the triple constraint (detect, mark, apply) is what interviewers test for. 🧠 Practice this problem yourself: 👉 https://codedive.in/set-matrix-zeroes 🚀 codedive.in — 207 curated DSA problems for AI/ML engineers.
