First you have to print the combination of cordinates on which n knights are place after 1 combination you have to give two space for the next combination of coodinates. In a combination each coordinate is seperated by a single space.
And after printing of all combination you have to print the number of that combination.

For Example -:
N = 2 ,
that means you have 2x2 grid and you have to place two knights such that no knight kill the other knight.

So the combination of indices will be
(0-0) (0-1)
(0-0) (1-0)
(0-0) (1-1)
(0-1) (1-0)
(0-1) (1-1)
(1-0) (1-1)

Now you have to just print using curly braces like
{0-0} {0-1} -> first combination and see there is space between the two coordinates
after that print two space and then next combination.

After all combination print the number of that combination.
