Problem Statement

There are a total of A+BA + B cats and dogs. Among them, AA are known to be cats, but the remaining BB are not known to be either cats or dogs.

Determine if it is possible that there are exactly XX cats among these A+BA + B animals.

Constraints

  • 1A1001 \leq A \leq 100
  • 1B1001 \leq B \leq 100
  • 1X2001 \leq X \leq 200
  • All values in input are integers.

Input

Input is given from Standard Input in the following format:

AA BB XX

Output

If it is possible that there are exactly XX cats, print YES; if it is impossible, print NO.

3 5 4
YES

If there are one cat and four dogs among the B=5B = 5 animals, there are X=4X = 4 cats in total.

2 2 6
NO

Even if all of the B=2B = 2 animals are cats, there are less than X=6X = 6 cats in total.

5 3 2
NO

Even if all of the B=3B = 3 animals are dogs, there are more than X=2X = 2 cats in total.
