This question was asked in Amazon interview few days back.
Please explain to me the part after building the SUM array.

Do we need to handle cases when the same string will appear again??
In that case we can sort individual array and remove duplicates.

const allows this function to be called on constant object.
So if someone creates an const obj of this class. Assignments can be done.

Building a max heap takes O(n) time irrespective of the array being sorted /
unsorted.
Can someone prove that. I already know that Heap can be constucted in
o(n*log(n)) time.

@DON: DFS should not be applied because, there can exist multiple paths

Otherwise you have to search for all possible paths which will be very

after second proecessing B is replaced by A
then why again this A is not being replaced by #define A macro..
why it is not going in an infinite loop...because i think there is no fiexed
order of
Can somebody explain how the macros are expanded regarding order in which
they are used...etc...
also explain this example :
