Google provided all the information about the interview, what to expect, and how to prepare. I got lots of links to read about the interview process, how they hire, their hiring philosophy, videos on what to expect during the interview, a link to a fantastic blog post from Steve Yagge, and suggestions to even read the book "Cracking the Coding Interview". This all removed the stress from the interview process and was very positive. Google really wants people to prepare and show their best instead of freaking out.

Given an m x n matrix containing only 0s and 1s, write code that finds a path of 1s from the first row to the last row.
