Bug Description

You have a starting number.
In each step, you take away a chunk that looks like “a power of two plus num2.”
After some steps, what’s left should exactly match a mix of powers of two.
So we test step counts (1 to 60).
For each count, we check if the remaining number is non-negative, big enough, and can be split into that many powers of two.
If yes, that count is the answer.
If no count works, then it’s impossible, so answer is -1.

Language Used for Code

Java

Code used for Submit/Run operation

Expected behavior

You start with a number num1.

Each move, you take away (2^i + num2) from it.

After k moves, the leftover must be made only from powers of two (like 1, 2, 4, 8...).

So we check for each k (1 to 60):

Is the leftover (num1 - k*num2) not negative?

Can it be broken into at most k powers of two?

Is it big enough for k moves?

The first k that works is the answer. If none works, answer is -1.

Thank you for reaching out and sharing your insights regarding the problem hints. It seems like you have a good grasp of the problem, and the approach you've described aligns well with the requirements of the challenge. The issue might lie in interpreting or implementing the solution rather than a discrepancy in the problem statement itself.

To assist you further, we suggest revisiting the implementation, ensuring that each operation correctly follows your plan regarding powers of two and subtraction using num2. As you work through it, consider checking out related discussions or the editorial for additional insights. If you believe there’s a discrepancy in how the problem should be approached versus what is provided, let us know with more specific details.

We appreciate your engagement with the platform and are here to support you on your problem-solving journey.
