Give me a code to count pairs ( i , j ) from an array such that and the other steps required given the following:
Count pairs ( i , j ) from an array such that | arr [ i ] | and | arr [ j ] | both lies between | arr [ i ] | Function to find pairs ( i , j ) such that | arr [ i ] | and | arr [ j ] | lies in between | arr [ i ] - arr [ j ] | and | arr [ i ] + arr [ j ] |.
Calculate absolute value of all array elements.
Sort the array.
Stores the count of pairs.
Traverse the array.
Increment left.
Add to the current count of pairs.
Print the answer.

#Here is code to count pairs ( i , j ) from an array such that and the other steps required.
 def findPairs ( arr , N ) :
	for i in range ( N ) :
		arr [ i ] = abs ( arr [ i ] )
	arr . sort ( )
	left = 0
	ans = 0
	for right in range ( N ) :
		while ( 2 * arr [ left ] < arr [ right ] ) :
			left += 1
		ans += ( right - left )
	print ( ans )
if __name__ == " _ _ main _ _ " :
	arr = [ 1 , 3 , 5 , 7 ]
	N = len ( arr )
	findPairs ( arr , N )
