Hi! Can anyone tell me what is array with only **pairwise distinct elements**? Does it means **unique elements**?

If possible Explain me with an Example!

Thanks in advance!

In short no number is present more than one time

It Means all the Numbers are distinct?

Yeah I guess so

All numbers are unique.No Duplicates.

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

Happy Coding !

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

Is List : {{1,2},{2,2},{2,3}} is pairwise-distinct? I think may be YES ?

Thanks in advance!

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