Solution: Confusing Number
Explore the concept of confusing numbers, which change into a different valid number when rotated 180 degrees. Understand the algorithm that reverses and converts digits using a mapping to solve this problem efficiently. Learn how to implement this check with O(log n) time and constant space complexity.
