I am a newbie on Codechef.

Any help will be appreciated

If it is given in the problem statement that :

βAll elements of the given array are pairwise distinct, does it mean that all the elements of the array are distinct ?β

Thanks in advance!

# What is the meaning of pairwise distinct integers?

**pairwise distinct means that,each element canβt be repeat more than once.**

Ex:

1 2 200 345 12 45 β> In this one,all are pairwise distinct.

1 2 200 200 12 12 β> This is not pairwise distinct since, 200 12 are occur 2 times each.

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 ).

To be pairwise distinct all the elements must be distinct?

In other words, pairwise distinct means, all of the elements are unique, none of them is repeated.
