Find The Parity Outlier

This problem brings back memories of a classic computer science homework: identifying the outlier in a list of numbers. Here's a clever solution that leverages the parity (even or odd) of the first few elements.

[*][s]1. [/s][s]**[/s]Parity Check:** We start by examining the parity of the first three numbers in the list. Even numbers result in a remainder of 0 when divided by 2, while odds yield a remainder of 1.

[*][s]2. [/s][s]**[/s]Majority Rules:** By storing these remainders in a list, we can determine the prevailing parity (even or odd) in the majority.

[*][s]3. [/s][s]**[/s]Find the Outlier:** Finally, we iterate through the entire list. The first number whose parity doesn't match the majority is our outlier!

This approach offers an efficient way to pinpoint the outlier, making it a valuable technique to have in your problem-solving toolbox.

Outlier in an array is a very good interview question too, it will get you sweating a bit. No, did I say good? I meant terrible!
