hello @raghav007
try to use set to remove redundant entries.

or
please raise this doubt from the question itself .
as that will give me problem id and using that id i can search for the problem over hackerblocks.

#4

is it possible to do it without set , I think it is when we don’t swap the identical elements, right?

#5

…

try this .
a) sort ur input
b) dont bactrack.
c) keep that if(i!=j && a[i]==a[j]) as it is.

and see if it is working or not
