HDU 6396 Swordsman --------2018 Multi-University Training Contest 7 (模拟+读入挂)

原题地址：

打怪升级 一开始有N个怪物；主角有K个能力；只有K个能力都击败怪物才能斩杀怪物并获得K个能力的增值；问最多能杀几个怪物；

做法：

用优先队列把怪物能力装进去；能力小放前面；

最重要的是数据量要用读入挂才能过；（读入挂太神奇了！！）

Problem Description

Lawson is a magic swordsman with  k kinds of magic attributes  v1,v2,v3,…,vk. Now Lawson is faced with  n monsters and the  i-th monster also has  k kinds of defensive attributes  ai,1,ai,2,ai,3,…,ai,k. If  v1≥ai,1 and  v2≥ai,2 and  v3≥ai,3 and  … and  vk≥ai,k, Lawson can kill the  i-th monster (each monster can be killed for at most one time) and get EXP from the battle, which means  vj will increase  bi,j for  j=1,2,3,…,k.
Now we want to know how many monsters Lawson can kill at most and how much Lawson's magic attributes can be maximized.

 

Input

There are multiple test cases. The first line of input contains an integer  T, indicating the number of test cases. For each test case:
The first line has two integers  n and  k ( 1≤n≤105,1≤k≤5).
The second line has  k non-negative integers (initial magic attributes)  v1,v2,v3,…,vk.
For the next  n lines, the  i-th line contains  2k non-negative integers  ai,1,ai,2,ai,3,…,ai,k,bi,1,bi,2,bi,3,…,bi,k.
It's guaranteed that all input integers are no more than  109 and  vj+∑i=1nbi,j≤109 for  j=1,2,3,…,k.

It is guaranteed that the sum of all n  ≤5×105.
The input data is very large so fast IO (like `fread`) is recommended.

 

Output

For each test case:
The first line has one integer which means the maximum number of monsters that can be killed by Lawson.
The second line has  k integers  v′1,v′2,v′3,…,v′k and the  i-th integer means maximum of the  i-th magic attibute.

 

Sample Input

1 4 3 7 1 1 5 5 2 6 3 1 24 1 1 1 2 1 0 4 1 5 1 1 6 0 1 5 3 1

 

Sample Output

3 23 8 4

Hint

For the sample, initial V = [7, 1, 1] ① kill monster #4 (6, 0, 1), V + [5, 3, 1] = [12, 4, 2] ② kill monster #3 (0, 4, 1), V + [5, 1, 1] = [17, 5, 3] ③ kill monster #1 (5, 5, 2), V + [6, 3, 1] = [23, 8, 4] After three battles, Lawson are still not able to kill monster #2 (24, 1, 1) because 23 < 24.
