Question

我将新模型和标签文件都复制到iOS应用程序中。应用程序参数如下：

3 
5 
65 66 67 68 128
3 2 7 8 -1 
4 5 5 7 101
3 5 6 9 102
2 5 6 9 -1
3 6 7 8 103

#include "iostream"
#include "fstream"
#include "string"


using namespace std;

int main(){
    int line=0;
    string l;
    int rows=5;
    int cols=6;
    int count=0;

    int **a=new int*[rows];// Dynamic array creation 

    for (int k=0;k<rows;k++){
        a[k]=new int[cols];
    }
    ifstream myfile ("23.txt"); // Reading file 

    if(myfile.is_open()){
        while(!myfile.eof() ){
            myfile>>l;
            cout << l;

            if ((l =="\n")||(l=="\r")){ 
                line++;
            }
            if (line ==2){
                for (int i=0;i<rows;i++){    //storing transition table in dynamically create array
                    for(int j=0;j<cols;j++){
                        a[i][j]=(int)l[j];
                        cout << l[j] << '\t';
                        count++;
                    } 
                }   
            }
        }
    }
    myfile.close();    //close the file
}

Answer 1

您应该注意一些事情，可以帮助您修复代码：

查看您的变量名：，例如，在代码的开头，您将使用空列表覆盖归因于major和minor的文件对象； < / li>
跟踪循环的运行情况：
- 如果您说要new_major的行数“是主文件中的行数的100倍”，那么您应该有一个内部循环可以迭代对于major file中的每一行，在外循环内进行100次操作（而不是遍历percent）；
- 您可能需要重新考虑生成final列表的循环。如果您的目标是使用“第7列” 来增加new_major行，那么如果您的外部循环遍历new_major行，您的代码就会变得更加清晰。然后，您可以使内部循环负责计算次要文件中的行数。
尝试逐步实现/测试您的代码：您清楚地想到了应该执行的步骤（因为您能够描述它们）。尝试一次实施和测试每个步骤。 “有点复杂” 问题总是可以分解成一些简单的小问题。
- 利用Python是一种解释性语言，可以更轻松，更快速地测试少量逻辑/代码；
- 例如，尝试在正确生成new_major文件之前尝试做其余的事情。如果这样做，您会注意到例如，new_major.append行未使用列一行的值。（您必须先分界线才能这些值）。

[额外]对解决方案的复杂性有所担心：在这种特殊情况下，复杂性可能对您来说不是问题，但让您自己思考这种问题总是很高兴的。想象一下，您有很长的minor和major文件，对其进行多次迭代可能会很昂贵。您可以做的一件事是根据第一列的值（可能使用dict）将次要文件“分解”为多个部分。因此，如果您对与minor行匹配的major条目进行计数，则只会迭代第一列值与参考行相同的条目。

Answer 2

您可以将sum与生成器表达式一起使用，以对符合条件的小型匹配行进行计数，然后使用str.join生成所需的输出：

major = '''chr1    +   1071396 1271396 LOC
chr12   +   1101483 1121483 MIR200B'''

minor = '''chr1    1071496 1071536 1
chr1    1071536 1071566 0
chr1    1073566 1073366 1
chr12   1101487 1101516 0
chr12   1101625 1101671 1'''

major, minor = ([l.split() for l in d.splitlines()] for d in (major, minor))

for name_major, sign, low, high, note in major:
    parts = list(range(int(low), int(high) + 1, (int(high) - int(low)) // 100))
    for part, (low, high) in enumerate(zip(parts, parts[1:]), 1):
        count = sum(1 for name_minor, n1, n2, _ in minor if name_major == name_minor and all(low <= int(n) <= high for n in (n1, n2)))
        print('\t'.join((name_major, sign, str(low), str(high), note, '%s_part%d' % (note, part), str(count))))

这将输出：

chr1    +   1071396 1073396 LOC LOC_part1   2
chr1    +   1073396 1075396 LOC LOC_part2   0
