#Here is code to maximize array sum after K negations and the other steps required.
 def sol ( arr , k ) :
	arr . sort ( )
	Sum = 0
	i = 0
	while ( k > 0 ) :
		if ( arr [ i ] >= 0 ) :
			k = 0
		else :
			arr [ i ] = ( - 1 ) * arr [ i ]
			k = k - 1
		i += 1
	for j in range ( len ( arr ) ) :
		Sum += arr [ j ]
	return Sum
arr = [ - 2 , 0 , 5 , - 1 , 2 ]
print ( sol ( arr , 4 ) )
