# Output Limit Exceeded - N-queens

• following is my code and the result on my laptop. however, i got output limit exceeded error. So, there is 352 solutions to 9-queens problem, my solution should be correct.

``````class Solution:
# @return a list of lists of string
def solveNQueens(self, n):
# translate
results = []
res = [['.']*n for i in range(n)]
for i in range(n):
res[a[i]][i] = 'Q'
results.append(res)
return results

def solve(self, curr, col, save, dim):
for i in range(0,dim):
# put Q in (i, col), check if it fits
if i in curr[:col]: # check row i of other columns
continue
curr[col] = i
fit = self.fit(curr,col,i,dim)
if fit:
if col == dim-1:
save.append(list(curr))
else:
self.solve(curr, col+1, save, dim)
curr[col] = dim

def fit(self, curr, col, row,dim): # check diag only
for i in range(1,col+1):

return True
