Daily Coding Problem: Problem #468 [Medium]

Good morning!

Here's a solution to yesterday's problem.

This is your coding interview problem for today.

This problem was asked by Facebook.

Given an N by N matrix, rotate it by 90 degrees clockwise.

For example, given the following matrix:

[[1, 2, 3],
 [4, 5, 6],
 [7, 8, 9]]

you should return:

[[7, 4, 1],
 [8, 5, 2],
 [9, 6, 3]]

Follow-up: What if you couldn't use any extra space?

We will be sending the solution tomorrow, along with tomorrow's question. As always, feel free to shoot us an email if there's anything we can help with.

Have a great day!
