Solution: Confusing Number

Understand how to identify confusing numbers by simulating a 180-degree rotation of digits. Learn the algorithm to process digits from right to left, rotate valid digits using a mapping, and compare the rotated number to the original. This lesson explains the implementation and analyzes time and space complexity.

Statement

A confusing number is a number that, when rotated 180 degrees, produces a valid yet different number.

Digits can be rotated 180180 degrees according to the following rules:

  • The digits 00 ...
