Solution: Confusing Number

Explore how to identify confusing numbers by simulating a 180-degree digit rotation. Learn the step-by-step algorithm to map digits, reverse order, and detect validity. This lesson helps you develop a clear approach to solve math and geometry problems involving number transformations efficiently.

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 ...
