[NOIP2006 提高组] 作业调度方案(修改)-编程知识

题目：

这里对于之前的题目进行修改记录。果然还是受不了等待，利用晚饭时间又看了这个题目。于是发现了问题。
之前的博客：https://blog.csdn.net/KLSZM/article/details/135522867?spm=1001.2014.3001.5501

问题修改描述

上午书写的代码中是按照工件的顺序号依次遍历，就是先将工件1的所有工序都放置完成后再进行下一个工件的录入。但是忽略了题目中所给出的顺序。所有的工件顺序在题目中已经给出。我们只需要放置好以后再抽空插入即可，修改了代码还是有一个测试点没有通过。后来下载了数据才发现是这个点的数据有问题！
以下是修改后的py代码

class Work:def __init__(self,n):self.num=nself.order_machine=[]self.time_machine=[]self.final=-1self.num_now=0def judge(t,x,y):global wore_linefor i in range(x,x+y):if wore_line[t][i]!=0:return Falsereturn Truedef add(t,x,y,p):global wore_linefor i in range(x,x+y):wore_line[t][i]=pif __name__=="__main__":num__max=120m, n = map(int, input().split())wore_line = [[0]*num__max for _ in range(m)]mapp = input()mapp=[int(intt) for intt in mapp.split()]work = []for item in range(2 * n):data = list(map(int, input().split()))if item < n:work.append(Work(item + 1))for k in range(m):work[item].order_machine.append(data[k])# work[item].order_machine = dataelse:for k in range(m):work[item-n].time_machine.append(data[k])# work[item - n].time_machine = dataflag=Truestep=0while flag:num_piece=mapp[step]-1num_piece_order=work[num_piece].num_nowkey_machine=work[num_piece].order_machine[num_piece_order]key_time=work[num_piece].time_machine[num_piece_order]# print("%d-%d:%d"%(num_piece+1,num_piece_order+1,key_time))for item in range(num__max-key_time):if judge(key_machine-1,item,key_time) and item>work[num_piece].final:add(key_machine-1,item,key_time,num_piece+1)work[num_piece].final=item+key_time-1break# for item in range(m):#     print(wore_line[item])# print()work[num_piece].num_now+=1step+=1if step==n*m:flag=False# for item in range(m):#     print(wore_line[item])# print()time_max=0time=0for item in range(m):for jtem in range(num__max-1,0,-1):if wore_line[item][jtem]!=0:time=jtem+1breakif time_max<time:time_max=timeprint(time_max)

请添加图片描述
第七个点的数据如下：

8 9
2 8 8 4 7 2 6 3 9 3 3 2 1 6 5 5 9 9 6 8 2 8 9 7 1 3 3 6 7 6 9 3 5 1 7 2 4 3 8 1 4 1 4 6 8 9 4 6 6 7 2 5 2 7 9 4 4 1 1 5 2 5 4 1 7 5 8 5 7 8 3 9

5 6 7 8 9 3 4 10
10 12 13 4 5 6 7 8
4 5 6 3 2 10 7 6

结果应是116，我得出的是112

通过对比可以发现，第七个工件的第一道工序的时间应该是10，而我的却是5.但是在输入中确实是5
在看一下输入数据，可以看到，第六个工件的数据为：

5 6 7 8 9 13 4 2 10

是9个数据.
这是不符合输入m=8的规矩的。而多输入的数据正好又是10，所有我认为应该是输入错误了。我一开始是直接将数据存入结构体中。但是发现修改成强制输入m组数据运行出来也是错的。。。

解决方案：

兄弟们这种数据这么离谱，咱不要自我折磨，直接跳过这组数据（狗头）
