Sum of Bitwise OR of all pairs in a given array | Returns value of " arr [ 0 ] ▁ | ▁ arr [ 1 ] ▁ + ▁ arr [ 0 ] ▁ | ▁ arr [ 2 ] ▁ + ▁ . . . ▁ arr [ i ] ▁ | ▁ arr [ j ] ▁ + ▁ . . . . . ▁ arr [ n - 2 ] ▁ | ▁ arr [ n - 1 ] ".
Consider all pairs ( arr [ i ] , arr [ j ) such that i < j.

#Here is code to sum of Bitwise OR of all pairs in a given array and the other steps required.
 def pairORSum ( arr , n ) :
	for i in range ( 0 , n ) :
		for j in range ( ( i + 1 ) , n ) :
			ans = ans + arr [ i ] | arr [ j ]
	return ans
arr = [ 1 , 2 , 3 , 4 ]
n = len ( arr )
print ( pairORSum ( arr , n ) )
