sorting - Algorithms to sort data from text files in ascending/descending order C# -


right, let me try explain stuck on , trying do! have multiple .txt files, large set of data inside them (one has days of week, dates, , others other data stocks) in descending order (so first piece of data of 1 .txt file matches first piece of data in .txt file).

i trying code read lines of text files (using file.readalllines), place read data big array (if possible) if user requests see data on "wednesday" or data in text files 01/03/1999 - 31/03/1999 , data show on command line (i added table - run code , you'll see mean) user has able search day or date , needs able sorted ascending , descending order using algorithm, in head, know need do, implementation struggle, i've tried array.list(), array.sort(), quicksort (wasn't useful @ all) , more have forgotten after 3 hours worth of trial , error.

i'm still quite new this, in terms of algorithms have explained it's @ least understandable open enough might others. if makes no sense, please ask questions , i'll answer them, might have confused myself in writing :p) in advance!

<!-- run code see table -->    <table style="width:100%">    <tr>      <td>date</td>      <td>day</td>       <td>open</td>      <td>close</td>      <td>difference</td>       <td>volume</td>    </tr>    <tr>      <td>01/03/1999</td>      <td>monday</td>       <td>312</td>      <td>320</td>      <td>...</td>       <td>...</td>    </tr>    <tr>      <td>10/03/1999</td>      <td>wednesday</td>       <td>301</td>      <td>289</td>      <td>...</td>       <td>...</td>    </tr>    <tr>      <td>19/03/1999/</td>      <td>friday</td>       <td>365</td>      <td>342</td>      <td>...</td>       <td>...</td>    </tr>  </table>

you not need write or implement sorting algorithms this, matter of parsing data object form.

file.readalllines dumps every line of file array, , not enough organize data meaningful way. need parse html deserialize file list of objects.

this point in right direction in regard parsing html: what best way parse html in c#?

you'll need create class property each of data fields.

after have turned files objects, , have verified data contained in objects, should have list or array of these items. can use linq extension method orderby sort data.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
