ABCPATH - ABC Path |
You will be given a 2-dimensional grid of letters. Find the length of the longest path of consecutive letters, starting at 'A'. Paths can step from one letter in the grid to any adjacent letter (horizontally, vertically, or diagonally).
For example, in the following grid, there are several paths from 'A' to 'D', but none from 'A' to 'E':
One such path is:
Input
Each test case will start with a line contains two integers H, W the height and width of the grid respectively 1 <= H, W <= 50. Then H lines follow each of W uppercase letters only. Input terminates with H = 0 and W = 0.
Output
For each test case print “Case C: X” without quotes where C is the case number starting with 1 and X is the solution.
Example
Sample Input: 4 3 ABE CFG BDH ABC 0 0 Sample Output: Case 1: 4

do i assume the the first character to be 'A'( i mean the [0][0]'th character ) or i will have to find it out by myself? |

CAREFULL WITH EDGE CASES LIKE NO 'A' OR JUST 1 'A'....AND BFS WITH LITTLE MODIFICATION WORKS !! |
