I am a newbie on Codechef.
Any help will be appreciated 
If it is given in the problem statement that :
“All elements of the given array are pairwise distinct, does it mean that all the elements of the array are distinct ?”
Thanks in advance!
It means that each pair of integers in the sequence are distinct. In other words, there are no 2 integers in the sequence that are the same.
Eg: 2,4,3 follows this whereas 2,4,3,4 does not ( because there is a pair of integers that are NOT distinct namely 3,3 ).
pairwise distinct means that,each element can’t be repeat more than once.
Ex:
1 2 200 345 12 45 —> In this one,all are pairwise distinct.
1 2 200 200 12 12 —> This is not pairwise distinct since, 200 12 are occur 2 times each.
