Problem Statement
You are given a string $S$. Output "YES" if $S$ contains 575, and "NO" otherwise.
Containing 575 means that there exists a substring $S_{sub}$ of $S$ such that $S_{sub}$ = "575".
Input
$S$
$1 \leq |S| \leq 100$
$S$ consists only of the alphanumeric characters 'a'-'z','A'-'Z','0'-'9'
Output
Output "YES" if $S$ contains 575, and "NO" otherwise.
Sample
Sample 1
Input
a575z
Output
YES
a575z
Sample 2
Input
57Z5
Output
NO
This does not count because there is a gap between 57 and 5.
Sample 3
Input
5757575
Output
YES
It is fine if there are many of them.
Sample 4
Input
0x1BF52
Output
NO
This is a suspicious hexadecimal number, so it does not count.
Sample 5
Input
MD5374d5502ef19c061204c2651c7f19f9b
Output
NO
Sites that calculate hash values sometimes add your input to their dictionaries (without asking), which is a little scary, isn't it?
