Code: Select all
4
0.01
0.05
0.05
0.07
$0.03
there are four students each spent 0.04(0.01+0.03), 0.04(0.05-0.01), 0.05 and 0.05(0.07-0.02) respectivily.
I found most of answers calculated the diff between average and each student' cost, like this
Code: Select all
if (average > students[i])
debit += average - students[i];
else
refund += student[i] - average;
if (debit > refund) return refund;
else return debit.
