Question by Ibrahim Mesecan.
Processing Cost
Assume that processing a list of items costs the
sum of differences between the item and the max
value in that series. For example if we are given
the series: 5 3 2 7, thus, the max of this series
is 7. Then, the processing cost of it is
= (7-5) + (7-3) + (7-2) + (7-7)
= 2 + 4 + 5 + 0 = 11.
Question:
Write a program that is going to read n rows of m
element series and then the program will find the
minimum processing cost.
Input specification
In the first line, you will be given two
numbers (n and m). Then, in the following n
lines, you will be given m integers
which are between -20000 and 20000 where
n and m are between 1 and 20000
Output specification
Show one integer: Minimum processing cost.
Sample Input I
3 4
7 1 7 9
4 10 8 8
9 2 6 3

Sample Input II
2 4
5 3 2 7
5 13 2 17
|
Sample Output I
10

Sample Output II
11

Explanation:
In sample input 1, there are 3 rows with 4 elements.
The max of first row is 9 and the processing cost of
it 12. The max of the second row is 10 with a total
processing cost of 10 (6+0+2+2).
Then the third series has the max of 9. And it’s
processing cost is 16. So, the second row has the
minimum processing cost: 10.
