-/**
- * 278. First Bad Version
- *
- * You are a product manager and currently leading a team to develop a new product.
- * Unfortunately, the latest version of your product fails the quality check.
- * Since each version is developed based on the previous version, all the versions after a bad version are also bad.
- *
- * Suppose you have n versions [1, 2, ..., n] and you want to find out the first bad one,
- * which causes all the following ones to be bad.
- *
- * You are given an API bool isBadVersion(version) which will return whether version is bad.
- * Implement a function to find the first bad version. You should minimize the number of calls to the API.
- *
- * Example:
- * Given n = 5, and version = 4 is the first bad version.
- * call isBadVersion(3) -> false
- * call isBadVersion(5) -> true
- * call isBadVersion(4) -> true
- * Then 4 is the first bad version.
