I have a log that consists of more than 100 million lines. Each line is just a data about user login, login time, etc. I want to sort them based on user login, and then if there is a tie based on login time, etc. However, I have limited memory, so don't think of storing all of them in an array. The memory can only hold n data where n is much smaller than 100 millions. You can access the disk though although it is much slower. How will you do it so that it is as efficient as possible?

Except experience related questions I was asked coding question and I was supposed to write the solution to the problem in any programming language in a simple web-based code editor. The question was: given and array of positive integers and another integer find whether there is a consecutive range in the array, so that the sum of integers in the range is equal to the given number. They put an emphasis on delivering working, efficient solution. In my opinion this kind of interview requires a thorough preparation.
