Google secret hiring foo-bar challenge codes

Many of you would be knowing, Google organizes a secret hiring foobar challenge, and I was very fortunate enough to get the links based on my search history. So I participated on it and have solved the 3rd level at present.

This repository is primarily focused on solving the google Foobar questions, and uploading them here for an overall idea of the contest and the questions standards.

Basically, the file structure goes like,

• Foobar 1 contains the answer of 1st level question(total 1 question)
• Foobar2 contain answers of 2nd level question(total 2 questions)
• Foobar3 contains answers of 3rd level questions(total 3 questions).
• Foobar4 contains answers of 3rd level questions(total 2 questions - yet to come)
• Foobar5 contains answers of 3rd level questions(total 1 question - yet to come)

You know wht! A fun fact is that, you also get a referral after completion of level 2&4, wherein you can invite your friends to participate for the challenge as well!

Note: I've currently completed level 3
