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’
Input:
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.
Output:
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.

If you are doing rabin-karp, and getting TLE, make sure you take care of the case when hash becomes -ve. Simply add mod to it. |
