Grokking the Coding Interview Patterns in C++

Solution: Confusing Number

Explore the concept of confusing numbers by understanding how digit rotation affects their values. Learn to implement an algorithm that identifies confusing numbers by reversing and transforming digits, and grasp the time and space complexity involved. This lesson aids in mastering pattern recognition useful in coding interviews.

We'll cover the following...

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 ...
