NAJPF - Pattern Find

Your task is so simple given a string and a pattern. You find the pattern on the given string. If found print how many time found the pattern and their index. Otherwise print ‘Not Found’


The input   line consists of a number T (1 ≤ T ≤ 50) test cases.

For each case given two string number  A,B. the string and the pattern  1 ≤|A|, |B| ≤10^6

All character will be lower case Latin character.  And |  | is the length of string.


For each case print the number  (found pattern from the given string) next line there position And Otherwise print 'Not Found' without quota.
There will a blank line between two cases.




ababab ab
aaaaa bbb
aafafaasf aaf

1 3 5

Not Found





Here all index is 1 base.

Weak test cases.
In my first attempt after finding a match I started from the end point of the match but still got an AC.
Then I realized that my solution won't work for `aaaa aa` case.

AC using KMP!
Testcases are weak! I used a slightly wrong version of KMP, and got AC

Tushar Roy's KMP lecture , probably the best tutorial. AC in one go. 1st KMP. Happy diwali :D
