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.

#include <stdio.h>

int main(int argc, char *argv[])
{
    int A;
    int B;
    int C;
    int X;

    if (scanf("%d %d %d", &A, &B, &X) < 100)
    {
        exit(1);
    }

    if (1 <= A && A <= 100 && 1 <= B && B <= 100 && 1 <= X && X <= 200)
    {

        C = A + B;

        if (X < A)
        {
            printf("NO\n");
