Given a string and patterns, find for each pattern the first position (1-indexed) where it appears in the string.
The first input line has a string of length n.
The next input line has an integer k: the number of patterns. Finally, there are k lines that describe the patterns.
The string and the patterns consist of characters a–z.
Print the first position for each pattern (or -1 if it does not appear at all).
- 1 \le n \le 10^5
- 1 \le k \le 5 \cdot 10^5
- the total length of the patterns is at most 5 \cdot 10^5
