If possible Explain me with an Example!
Thanks in advance!

if you choose any 2 element from an array they couldnot be the same.

Suppose we have a list of elements where every element is of the form [a,b]
List : { {1,2} , {2,3} , {3,4} } // This list is pairwise-distinct.
List : { {1,2} , {2,3} , {3,4} , {1,2} } // This list is not pairwise-distinct. Sice the pair {1,2} comes twice in the list.
Hope that makes sense :slight_smile:

Happy Coding ! :sunglasses:

It means every coordinate is unique.
For any two points, both x and y coordinate cannot be same.

| (X,Y) | = | [X,Y] |

Hi @aon_23 :slight_smile:
Is List : {{1,2},{2,2},{2,3}} is pairwise-distinct? I think may be YES ?
Thanks in advance! :slight_smile:

yes it is. Since there’s no pair which is repeating.
