Optimizing Decreases - Minimizing Product of Two Numbers

TLDRGiven two numbers and the number of operations, find the minimum product after performing n operations to either of the numbers, subject to a constraint.

Key insights

💡By decreasing the smaller number as much as possible and then decreasing the larger number, we can minimize the product.

🧠We can solve the problem twice by first decreasing from a and then from b, and then swap the positions and the constraint.

🔄Swapping the positions and constraints allows us to reuse the same code without overcomplicating the implementation.

Q&A

What is the approach to solve this problem?

The approach is to first decrease as much as possible from one number and then from the other number, and finally swap the positions and the constraint.

How does swapping positions and constraints help?

Swapping positions and constraints allows us to reuse the same code without overcomplicating the implementation.

What is the insight behind minimizing the product?

By decreasing the smaller number first and then the larger number, we can minimize the overall product.
