Q. Which of the following statements are true ?
i) practical application of XOR linked lists are in environments with limited space requirements, such as embedded devices.

ii)xor lists are not suitable because most garbage collectors will fail to work properly with classes or structures that don’t contain literal pointers

iii)in order to calculate the address of the next node you need to remember the address of the previous node

iv)xor lists are much efficient than single, doubly linked lists and arrays

Q. 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.

To implement above algorithm which datastructure is better and why ?
