Problem Statement

There are X+Y+Z people, conveniently numbered 1 through X+Y+Z.
Person i has A_i gold coins, B_i silver coins and C_i bronze coins.

Snuke is thinking of getting gold coins from X of those people, silver coins from Y of the people and bronze coins from Z of the people.
It is not possible to get two or more different colors of coins from a single person.
On the other hand, a person will give all of his/her coins of the color specified by Snuke.

Snuke would like to maximize the total number of coins of all colors he gets.
Find the maximum possible number of coins.

Constraints

1 \leq X

1 \leq Y

1 \leq Z

X+Y+Z \leq 10^5

1 \leq A_i \leq 10^9

1 \leq B_i \leq 10^9

1 \leq C_i \leq 10^9

Input

Input is given from Standard Input in the following format:

X Y Z
A_1 B_1 C_1
A_2 B_2 C_2
:
A_{X+Y+Z} B_{X+Y+Z} C_{X+Y+Z}

Output

Print the maximum possible total number of coins of all colors he gets.

Sample Input 1

1 2 1
2 4 4
3 2 1
7 6 7
5 2 3

Sample Output 1

18

Get silver coins from Person 1, silver coins from Person 2, bronze coins from Person 3 and gold coins from Person 4.
In this case, the total number of coins will be 4+2+7+5=18.
It is not possible to get 19 or more coins, and the answer is therefore 18.

Sample Input 2

3 3 2
16 17 1
2 7 5
2 16 12
17 7 7
13 2 10
12 18 3
16 15 19
5 6 2

Sample Output 2

110
