#Here is code to find number of pairs in an array such that their XOR is 0 and the other steps required.
 def calculate ( a ) :
	a . sort ( )
	count = 1
	answer = 0
	for i in range ( 1 , len ( a ) ) :
		if a [ i ] == a [ i - 1 ] :
			count += 1
		else :
			answer = answer + count * ( count - 1 ) // 2
			count = 1
	answer = answer + count * ( count - 1 ) // 2
	return answer
if __name__ == ' _ _ main _ _ ' :
	a = [ 1 , 2 , 1 , 2 , 4 ]
	print ( calculate ( a ) )
