Young programmer Vasya writes a "hello world" program in a simple programming language. Program consists of a single line and should look like that:
print("Hello,World")Vasya is very bad at typing. While trying to enter the line above,
he pressed letter keys L times, special character keys C times
(including quotes, comma and parentheses).
Vasya also pressed backspace key B times, erasing a single character every time.
Your program must determine if it is possible in principle that Vasya achieved the exact text above.
Input file contains integers L, C, B.
Output file must contain a single line YES or NO.
0 ≤ L, C, B ≤ 100
L + C ≥ B
