DIFFICULTY

HARD!! // Actually it is CAKEWALK !! Nice Scare :D

EXPLANATION

This was the easiest problem of the set. All one had to do is to examine all start positions (i,j) and make one horizontal check for 5 consecutive characters and one vertical scan. Refer to setter's or testers solution for a reference. Somethings to take care of :

• Match performed should be case-insensitive.
• Beware of boundaries. Check (i,j) for horizontal match only if there are 5 or more characters. Same for vertical.
• Be sure not to go out of the boundary - off by 1 errors are common.
