### 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.
