Product Support Engineer was asked...24 March 2014

A question that I have seen several times with regard to Palantir: You have an array of integers where each integer has a duplicate somewhere in the array, apart from one. How would you find the non-duplicated integer? How many times would you need to iterate through the array given your solution (didn't need to know Big O notation)?

2 Answers

Much more creative method: XOR each element in the array, the result will be the non-duplicate element. Less

Initialise empty set. Iterate through the original array. If the integer exists in the set, delete it from the set, else insert it into the set. At the end, you will end up with the one non-duplicated integer sitting in the set. Less

I was extremely qualified and they seemed very impressed with our conversations. However after all the phone interviews the recruiter called me with an update that I was in the running with two other candidates and then I never heard from them again. I found that very unprofessional and now a few months have gone by. I hate to see how they treat their actual employees. Less
