c# - Is it necessary to implement a BST with both keys and values? -

-

is necessary implement bst both keys , values? can implement bst has method calls such following, in make comparison @ each node of whether traversal should go left node or right node based upon v value:

public class bst<v> {     public void insert(v value)     {         //implementation     }      public v remove(v value)     {         //implementation     }      //other methods }

or, can implement bst such has method calls following, in k keys comparing determination of whether traverse left node or right node:

public class bst<k key, v value> {     public void insert(k key, v value)     {         //implementation     }      //which of following appropriate method signature?     public v remove(k key)     {         //implementation     }     //or?     public v remove(v value)     {         //implementation     }      //other methods }

not using key value fine. however, tree become immutable if this. modifying value no longer safe since imbalance tree. have enforce providing property getter node value.

c++ - Convert big endian to little endian when reading from a binary file -

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...

i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() .
