Sorting Scripture References -


i'm working on csci capstone focusing on text-searching through bible and, because of nature of program, returning unordered list of scripture references formatted such: "nameofbook chapnum: versenum".

after list of references, need sort them on 3 fields: name, chapter, , verse, in order, , i'm hoping avoid using o(n^3) algorithm. have code sorts each reference on book name, o(n), don't know go here...

suggestions?

edit: i'm working in java arrays , looking @ storing sorted data text file can accessed later on.

if want have single sort name, chapter, , verse, can either set sort uses 3 of things key sorting, or can use "stable sort" , sort verse, chapter, name.

here's pseudocode in python. it's real python code except don't have definitions parse_code(), get_name(), get_chapter(), or get_verse().

lst = [] x in parse_code(input_file):     name = get_name(x)     chapter = get_chapter(x)     verse = get_verse(x)     tup = (name, chapter, verse)     lst.append(tup)  lst.sort()  # automatically want

when have list made of tuples, , sort list, python sort based on first item in tuple, followed second, followed third.

on other hand, if trying build 3 different indexes, maybe simplest implementation stash data in database, , put index on each of name, chapter, , verse. use sqlite database; project size of text in bible think work well.

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua...
