MCQ

Given 10,8,6,7,9
swap the above numbers such that finally you got 6,7,8,9,10
so now reverse 10
9,7,6,8,10
now reverse 9
8,6,7,9,10
7,6,8,9,10
6,7,8,9,10
at this point 6 is ahead so no more reversing can be done so stop.

arrays. because we can swap elements easily

xor linked list. because there is no overhead of pointers and so memory is saved

doubly linked list. because you can traverse back and forth
