Solution: First Bad Version

Explore how to use modified binary search to find the first bad version in a sequence where each version builds on the previous one. This lesson helps you implement a logarithmic time complexity solution that reduces calls to the isBadVersion API, ensuring efficient and accurate problem-solving for coding interviews.
