The ACM team's fleeting study of mathematics is not very thorough, but stubborn he still want to go in.
Browsing the Web page suddenly saw someone on the internet with rose petals to spell 5,213 numbers, suddenly feel good romantic, because every boy will inadvertently become a romantic manufacturer. Since then, the time to go everywhere can see 5, 2, 13 numbers, he was angry, and now he wants to know how many of the consecutive number of the total contains the three numbers. For example, 12356 even one, and 5111 does not count. In particular, if he sees 5,213 numbers appearing in succession, it will be particularly furious. For example 35210.
