Hello everyone,

Can anyone tell me why the answer of this problem:
1283E - New Year Parties

to this test case:
9
9 5 7 9 6 4 6 4 8

is:
2 8

isn't 3 8 ?

Thanks in advanced.

If we sort the array then it is like 4 4 5 6 6 7 8 9 9 We can convert it like 5 5 5 5 5 8 8 8 8 So the minimum answer is 2 instead of 3
