[Output]
NO
[Explain]
If unfortunately, we get color {4,4,4,4,3} from drawer 1 and {1,1,1,1,2,2} from drawer 2 we won't have a pair of gloves of the same kind.

[Input]
4
1 2 3 4

Note

If Ninetail tell you she wants to get gloves more than the sum of gloves in the drawer(ie. $A\gt \sum_{i=1}^NA_i$ or for B). Just treat she is drunk and print "YES".
