问题 I have a List of objects in C#. All the objects contain properties code1 and code2 (among other properties). The list of objects is in no particular order. I need to sort the list of objects by their code1 and code2 properties. Example: List -> object = id, name, code1, code2, hours, amount. Example code 1 = 004 Example code 2 = 001, 002, 003, 004, 016 Example code 1 = 005 Example code 2 = 001, 002, 003, 004 So after the sort I would want the objects in the following order 004 001 004 002 004

问题 I'm looking for a simple, easy to understand algorithm to alphabetically sort an array of characters in C. 回答1: characters in C have numeric values that happen to be in order, so you just treat your characters like integers. the C standard library includes a 'qsort' function. Use that ( man qsort on a linux-like system). You might have to convert upper-case letters to lowercase to simplify things, but that's trivial. If you want to understand the quicksort algorithm (that's the one you should

问题 The output from a command is sent as a CSV list of UUIDs. The UUIDs are not sorted however, so it's very difficult to tell if a line is unique. I would like to sort each line by the value between the commas, and then uniq the lines. I know I could hack something up with awk , but I was hoping for a cleaner/more elegant one-liner. Any ideas? EDIT Here is some sample data: 9166e19c-4794-467e-baad-3f8c2f2656cb,f5553f54-589b-4afd-a8e0-2239b23dc138,ee721e70-a7e2-4da2-a2b0-22bec3432c3d,7e17bf09

问题 I want to sort a list of strings in reverse order, e.g.: my_list = ['aaa', 'bbb', 'ccc'] expected result: ['ccc', 'bbb', 'aaa'] I don't want to use sorted(my_list, reverse=True) , because in more complex case when filtering by two values it would not work. For example: my_list2 = [('aaa', 'bbb'), ('aaa', 'ccc'), ('bbb', 'aaa'), ('bbb', 'ccc')] expected result would be: [('bbb', 'aaa'), ('bbb', 'ccc'), ('aaa', 'bbb'), ('aaa', 'ccc')] sorted(my_list2, reverse=True) returns: [('bbb', 'ccc'), (

问题 How do I parse this? The array is unnamed, the objects are unnamed? I also need to sort it and find overlaps(identify conflicts) between events IF you guys have any advice there too it will be a huge help for me.
