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.

AC in one go !!

the tc seems too weak, brute force still pass

AC in one go! 0.04 secs using KMP and global declaration of strings.

AC in one go using Rabin Karp

Learned both rabin karp and kmp :)

weak test cases I later came to know that my code was wrong but it passed

I'm getting TLE inspite of using the KMP algorithm (coded in Java), can't figure out why ...

Using string find function , I get the Time complexity of 0.02 seconds.

using kmp O(n+m) 0.38 sec
