Write a function checkvertical(board, word, row, col), which returns True if the word word can be added to the board starting at position board[row][col] and going down. The restrictions are (1) it has to fit entirely on the board, (2) it has to intersect and match with one or more non-blank letters on the board, and (3) it cannot change any letters on the board, other than blanks (that is, overlapping mismatches are not allowed).

My program isn't working :( Can anyone fix the program?

My program:

def checkvertical(board, word, row, col):

if len(word) > 20 - row:

return False

matchesoneletter = False

for k in range(len(word)):

wordletter = word[k]

boardletter = board[row + k][col]

if wordletter == boardletter:

matchesoneletter = True

if boardletter == blank:

continue

elif boardletter != wordletter:

return False

return matchesoneletter

Expert Solution

def checkvertical(board, word, row, col):
   #considering board size of 20 x 20 seeing your code.
   #if the len(word) doesn't fit vertically at that position.
   if len(word)>20-row:
       return False
   #else check for each letter in word matches with the
   #letter on the bord starting index(row) or there is blank space
   #if not so exit by returning false
   #if it successfully runs till the end, it implies,
   #the word can be fit there.
   for i in range(len(word)):
       # here i am considering -1 representing blank space in your board
       # if not so change that value
       if word[i] == board[row+i][col] or board[row+i][col]==-1:
           continue
       else:
           return False
   return True
