RelayHealth Front End Engineer interview questions

I applied through University Job Fair. A week late I got an email from HR/Recruiter, initial email screening took place, where they asked about my interests and Visa status. After that was the first round. I went to the Emeryville office. For the first round, there were 2 of them to interview me. One of them was a Sr. Software Engineer and the other was one from the front-end team. The Sr. Software Engineer asked me basic java questions and questions from my resume. The other person who was from the front-end team asked me coding questions. Questions are below. Then on the next Monday i got a reject.
