The recruiter was amazing. They helped me understand the process clearly and move on to the feedback positively. I just had a phone interview.

First, I had to introduce myself and one of my projects. Then, I was asked to code. It was a difficult question for me and took a lot of time to think through. Of course, there was no on-site interview.

Find and output the given number's shortest square sum.

For example: Input: 12 = 2^2 + 2^2 + 2^2 (not 3^2 + 1^2 + 1^2 + 1^2) Output: {2 2 2}
