| * I am brianstorti (https://keybase.io/brianstorti) on keybase. | |
| * I have a public key whose fingerprint is AC83 2A13 C81A FD98 4C06 4FF4 01CF 37BD BDBE 035C | |
| To claim this, I am signing this object: |
| ; with "require", I need to use the namespace-qualified name | |
| (require 'examples.foo) | |
| ("bar" examples.foo/function-name) | |
| ; I can use "refer" to avoid that | |
| (require 'examples.foo) | |
| (refer 'examples.foo) | |
| ("bar" function-name) | |
| ; or I can use "use", that will do both the steps for me |
| ; sum the square of the parameters. | |

Breadth-first search (BFS) is a strategy for searching in a graph.
The BFS begins at a root node and inspects all the neighboring nodes. Then for each of those neighbor nodes in turn, it inspects their neighbor nodes which were unvisited, and so on.
This image shows the order in which the nodes are expanded:
| class Node | |
| attr_reader :name | |
| def initialize(name) | |
| @name = name | |
| @descendants = [] | |
| end | |
| def add_edge(descendant, weight) | |
| @descendants << {:node => descendant, :weight => weight} |
| man() { | |
| PAGER="/bin/sh -c \"col -b | vim -R -c 'set ft=man' -\"" command man $@ | |
| } |
