There was a question based on connected components in a graph to solve. Initially, I told my approach to the interviewer and then I was able to solve the question partially. He asked me some other basic questions based on the code I had written. He then moved on to another question based on arrays(two elements in an array whose sum is zero). To solve this question, I explained my three approaches(naive, two pointer, hashmap implementations).
