🔥 Maximum Running Time of N Computers – Full Explanation | Binary Search + Greedy Logic
In this video, we solve an important coding interview problem where we need to find the maximum number of minutes all N computers can run simultaneously using a set of batteries.
We break the entire logic step-by-step, including:
✔ Deep intuition
✔ Why binary search works
✔ Feasibility check
✔ Line-by-line code explanation
✔ Dry run
✔ Complexity analysis
This problem is commonly asked in FAANG, especially in Amazon, Google, and Meta interviews.
Watch till the end to understand the full approach clearly!
