Using Python's built-in defaultdict we can easily define a tree data structure:
def tree(): return defaultdict(tree)
That's it!
#!/usr/bin/env python | |
# -*- coding: utf-8 -*- | |
import sys | |
# This is the framework for graphs we use on this work | |
import networkx as nx | |
# Tool to determine wether elements are on the same set | |
from networkx.utils import UnionFind | |
# We need this in python to "clone" objects | |
import copy |

# The new GDB commands: | |
# are entirely non instrumental | |
# do not depend on any "inline"(s) - e.g. size(), [], etc | |
# are extremely tolerant to debugger settings | |

# This file should be "included" in .gdbinit as following: | |
# source stl-views.gdb or just paste it into your .gdbinit file |

Searches a graph and yields all the minimum spanning trees in order of increasing cost. | |
This could be used to solve minimum spanning trees with constraints by yielding trees until | |
we reach the first one which satisfies a constraint. | |
For example it could solve the degree constrained minimum spanning tree DCMST | |

Prerequisites:
Software components used:
When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:
const Article = require('../../../../app/models/article');
Those suck for maintenance and they're ugly.

This document describes the C# language features currently featured in the March CTP. There's also discussion of a few of the VB features in the preview, where those are intended to be eventually implemented in C# as well.
Note that we have more language features planned that are not yet implemented. So look out for more to come in future CTPs and eventually a shipping version of C#.
I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!
