Can you provide a code to count of unordered pairs ( x , y ) of Array which satisfy given equation and the other steps required given the following:
Count of unordered pairs ( x , y ) of Array which satisfy given equation | Return the number of unordered pairs satisfying the conditions.
ans stores the number of unordered pairs.
Making each value of array to positive.
Sort the array.
For each index calculating the right boundary for the unordered pairs.
Return the final result.

#Here is code to count of unordered pairs ( x , y ) of Array which satisfy given equation and the other steps required.
 def numPairs ( a , n ) :
	ans = 0
	for i in range ( n ) :
		a [ i ] = abs ( a [ i ] )
	a . sort ( )
	for i in range ( n ) :
		index = 0
		for j in range ( i + 1 , n ) :
			if ( 2 * a [ i ] >= a [ j - 1 ] and 2 * a [ i ] < a [ j ] ) :
				index = j
		if index == 0 :
			index = n
		ans += index - i - 1
	return ans
a = [ 3 , 6 ]
n = len ( a )
print ( numPairs ( a , n ) )
