I applied on the website of Epic. After two or three weeks, a recruiter contacted me and scheduled a phone interview. They also invited me to do the online assessment before or shortly after the phone interview, which would speed up the process.

The phone interview took 45 minutes. The interviewer first verified my degree, GPA, and other information, then projects on the resume.

After that, I scheduled the online assessment and took it.

Define an additive number as 112, 224, 1123, 121224, and so on. In these examples:

• 1 + 1 = 2
• 2 + 2 = 4
• 1 + 1 = 2, and 1 + 2 = 3.

Also, the first two numbers should always be equal.

Given a range, print all additive numbers within that range (inclusive).
