I think k — sum1 < 0 for some cases .
Simply do this .
n = 4
1 2 3 4
set1 : 1 4
set2 : 2 3
n = 6
1 2 3 4 5 6
The ans will be no because odd number of pairs .
n = 8
1 2 3 4 5 6 7 8
set1 : 1 8 3 6
set2 : 2 7 4 5
Property of arithmetic progression .
Try taking n as long long. Your code is having integer overflow when you take n >= 1e5
Thanks both so much
