The interview was kind of straightforward . 1st round : 1) Given 2 million stars and their distance from earth, how will you pick out the 200 closest stars? Assume that you can have only 10000 stars at a time in memory. Was asked to write code for this question.. 2nd round 2) Remove repeating characters from a string. Eg: "Green Apple" O/p: Grn Apl No extra memory allowed - no hashing , no extra arrays. You may use extra variables.
