#Here is code to ways to place 4 items in n ^ 2 positions such that no row / column contains more than one and the other steps required.
 def NumbersofWays ( n ) :
	x = ( n * ( n - 1 ) * ( n - 2 ) * ( n - 3 ) ) // ( 4 * 3 * 2 * 1 )
	y = n * ( n - 1 ) * ( n - 2 ) * ( n - 3 )
	return x * y
n = 4
print ( NumbersofWays ( n ) )
