Hello @hrithik-1 yes there are errors in it as well.
basically we have to check the diagomals only in it.
like for the left diagonal we will start from the current location and we will decrement it till both these variables are greater then zero.
and for the right diagional we haver to check in the way like from the current location we will start decrememting the row and start incrementing the column till the rows reaches to the first row and the columns reaches to the end column.
and other than this we have to check if it has any queen in that particular column as well.
if you will find any queen in any row or column then we will return false and try for any other position.
if you have any other doubt you can ask here:
