WebApr 9, 2024 · Next thing to notice here would be to see that if it is possible to get an answer = x then it is also definitely possible to get answer >= x due to the min max nature of the problem. So we could apply binary search on the answer. Call it mid. Having stated that it is still tricky to notice on how we will go left or right in our binary search.
