I solved it with backtracking:

1) Start in the leftmost column
2) If all queens are placed
return true
3) Try all rows in the current column. 
Do following for every tried row.
a) If the queen can be placed safely in this row 
then mark this [row, column] as part of the 
solution and recursively check if placing
queen here leads to a solution.
b) If placing the queen in [row, column] leads to
a solution then return true.
c) If placing queen doesn't lead to a solution then
unmark this [row, column] (Backtrack) and go to 
step (a) to try other rows.
4) If all rows have been tried and nothing worked,
return false to trigger backtracking.
