In the United States of America, telephone numbers within an area code consist of seven digits: the prefix number is the first three digits and the line number is the last four digits. Traditionally, the $555$ prefix number has been used to provide directory information and assistance as in the following examples:
 - 555-1212
 - 555-9876
 - 555-5000
 - 555-7777

Telephone company switching hardware would detect the $555$ prefix and route the call to a directory information operator. Nowadays, telephone switching is done digitally and somewhere along the line a computer decides where to route calls.

For this problem, write a program that determines if a supplied seven-digit telephone number should be routed to the directory information operator, that is, the prefix number is $555$.

-----Input-----
The single line of input contains a single integer $n$ ($1000000 \le n \le 9999999$), which is a telephone number.

-----Output-----
Output a single integer, which is $1$ if the number should be routed to the directory information operator, or $0$ if the number should not be routed to the directory information operator.

-----Examples-----
Sample Input 1:
5551212
Sample Output 1:
1

Sample Input 2:
5519876
Sample Output 2:
0

Sample Input 3:
5055555
Sample Output 3:
0
