Write me a code to represent n as the sum of exactly k powers of two and the other steps required given the following:
Represent n as the sum of exactly k powers of two | Set 2 | Function to print k numbers which are powers of two and whose sum is equal to n.
Initialising the sum with k.
Initialising an array A with k elements and filling all elements with 1.
Iterating A [ ] from k - 1 to 0.
Update sum and A [ i ] till sum + A [ i ] is less than equal to n.
Impossible to find the combination.
Possible solution is stored in A [ ].

#Here is code to represent n as the sum of exactly k powers of two and the other steps required.
 def FindAllElements ( n , k ) :
	sum = k
	A = [ 1 for i in range ( k ) ]
	i = k - 1
	while ( i >= 0 ) :
		while ( sum + A [ i ] <= n ) :
			sum += A [ i ]
			A [ i ] *= 2
		i -= 1
	if ( sum != n ) :
		print ( " Impossible " )
	else :
		for i in range ( 0 , k , 1 ) :
			print ( A [ i ] , end = ' ▁ ' )

	k = 6
	FindAllElements ( n , k )
