Maximum difference between group of k | utility function for array sum.
function for finding maximum group difference of array.
sort the array.
find array sum.
difference for k - smallest diff1 = ( arraysum - k_smallest ) - k_smallest.
reverse array for finding sum 0f 1 st k - largest.
difference for k - largest diff2 = ( arraysum - k_largest ) - k_largest.
return maximum difference value.
