I think the median can be found in O(n), because in O(n) we can merge the arrays into a single sorted array and in O(1) we can find the middle element of the array. Am I correct ??

Doubt
I have a general doubt. If we have a wrong question in GATE paper then what we need to do? should we attempt it or leave it. because if question is wrong marks should be given to all the students who have attempted that question or gate people will simpy ignore that question and don't do any thing.

Computer Networking
Is there any way / Approach or any idea to how to learn port addresses for different protocols. I have seen many questions in test series regarding ports. I have never seen GATE asking such questions. But what if it comes. If anyone of you, has any technique to by heart them, then please share here . It will be beneficial to all . Thanks !!!

Operating System
Consider a paging system which stores its two-level page table in memory and its 16 most recently referenced entries in a TLB. If, a memory access takes 80 nsec, a TLB lookup takes 20 nsec and a page swap time takes 5000 nsec, how long does a data item take to access if the TLB hit rate is 95% and the page fault rate is 10% ?
