1. Asked about my profile 2. Asked to write the programm to sort and remove duplicate in O(n) of complexity. I said it is not possible to do so as Every sorting algo at least requires O(nlogn) of complexity. : Not very convience with my answer he said he can use treemap , but I said itself it must be using quick sort or so. 3. Asked me to write the longest pallindrome : I wrote the programme with O(n2) of complexity he said there should be a better algo to solve it in much effective way.
