Can you provide a code to maximum sum of values in a given range of an Array for Q queries when shuffling is allowed and the other steps required given the following:
Maximum sum of values in a given range of an Array for Q queries when shuffling is allowed | Function to find the maximum sum of all subarrays.
Initialize maxsum and prefixArray.
Find the frequency using prefix Array.
Perform prefix sum.
Sort both arrays to get a greedy result.
Finally multiply largest frequency with largest array element ..
Return the answer.
Driver Code.
Initial Array.
Subarrays.

#Here is code to maximum sum of values in a given range of an Array for Q queries when shuffling is allowed and the other steps required.
 def maximumSubarraySum ( a , n , subarrays ) :
	maxsum = 0
	prefixArray = [ 0 ] * n
	for i in range ( len ( subarrays ) ) :
		prefixArray [ subarrays [ i ] [ 0 ] - 1 ] += 1
		prefixArray [ subarrays [ i ] [ 1 ] ] -= 1
	for i in range ( 1 , n ) :
		prefixArray [ i ] += prefixArray [ i - 1 ]
	prefixArray . sort ( )
	prefixArray . reverse ( )
	a . sort ( )
	a . reverse ( )
	for i in range ( n ) :
		maxsum += a [ i ] * prefixArray [ i ]
	return maxsum
n = 6
a = [ 4 , 1 , 2 , 1 , 9 , 2 ]
subarrays = [ [ 1 , 2 ] , [ 1 , 3 ] , [ 1 , 4 ] , [ 3 , 4 ] ]
print ( maximumSubarraySum ( a , n , subarrays ) )
