InterviewBit is giving wrong solution I guess


#1

Support we take 5 and 7
So here the answer would be 1
but interviewbit is giving 2 as answer.

Another example:
2,3,6 = output should be 4 but interviewbit is saying 8
Why is that.


#2

Its actually correct
The question says we have to cosider all pairs
So in 5 7 the answer is 2 because (5,7) and (7,5) are different
Similarly every pair occurs twice hence the final answer is doubled.


#3

(5,7) and (7,5) are not different, problem statement is wrong

[1,2,3] now tell me how many pairs are there?


#4

{ (1,1), (1, 2), (1, 3), (2, 1), (2, 2), (2, 3), (3, 1), (3, 2), (3, 3) } we will have a total of these 9 pairs.


#5

{ (1,1), (1, 2), (1, 3), (2, 1), (2, 2), (2, 3), (3, 1), (3, 2), (3, 3) } we will have a total of these 9 pairs.
