Find the longest common substring between the two informed Strings. The substring can be any part of the String, including the entire String. If there is no common substring, return 0. The search is case sensitive ('x' != 'X').
Input
The input contains several test cases. Each test case is composed by two lines that contains a string each. Both input Strings will contain between 1 and 50, inclusive, letters (a-z, A-Z), and/or spaces.
Output
The length of the longest common substring between the two Strings.
Example
Input: abcdef
cdofhij

FOUR
abracadabra

O(n*m) worked for me in C++. n and m being the string lengths. Last edit: 2015-09-25 14:37:33 |

how many test cases will be given? what is the required complexity range? |

@ritesh: U have to find the longest common substring. Substring is contiguous occurence of letters in both the strings. U are confusing substring with subsequence. |

shouldn't the first output be 3 as there are three common elements viz. c,d,f ? |
