Problem Statement

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

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

Constraints

1 \leq A \leq 100

1 \leq B \leq 100

1 \leq X \leq 200

All values in input are integers.

Input

Input is given from Standard Input in the following format:

A B X

Output

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

Sample Input 1

3 5 4

Sample Output 1

YES

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

Sample Input 2

2 2 6

Sample Output 2

NO

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

Sample Input 3

5 3 2

Sample Output 3

NO

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

Solution in JavaScript (node.js v5.12) (judge verdict: Accepted)

function main (input) {
  const A = parseInt(input.split(' ')[0],10);
  const B = parseInt(input.split(' ')[1],10);
  const X = parseInt(input.split(' ')[2],10);

  if (X > A+B) {
    console.log('NO');
  } else if (A > X) {
    console.log('NO');
  } else {
    console.log('YES');
  }
}

main(require('fs').readFileSync('/dev/stdin', 'utf8'));
