i had one place ask me during an interview to determine if a string is a rotation of another, so i go and write a hacky longest common substring algo and get 'er done as they say

apparently it's one of those trick ones where you just concat the string and to a strstr. shame on me for not reading the "tricks of the trade: ace the programming interview!!!!" book

it's nice to know that stuff like this is built into python. permutations is another cool one.

dictionaries and maps are different thing. the c# Dictionary type is a dictionary, not a map.

i think perl/ruby are wrong here cause it's confusing as poo poo (even tho they are implemented with hashing algos)

map is the perfect name cause it's what we've been calling that concept (function from X->Y) since set theory got all hollywood

# ? Apr 26, 2012 19:19

Map is correct because it is a mapping of keys to values

Dictionary is incorrect because dictionaries are a specific type of map

Hash is incorrect because it is a specific implementation of a map.

_.each(string.split(""), function(char) { counts[char] = counts[char]+1 || 1 }); is a cool one-liner but it's not like there's anything with just using a for loop

personally when i look at code samples i'm looking at their coding style. you can learn a lot about a person by looking at their code.

for example, here is some code from a real candidate:
code:
 if if if
this was sent by the candidate in response to my request for code that the candidate was particularly proud of, that showed their skills. would you give this person a job? i wouldn't.

Code samples are also a way for candidates to show their enthusiasm - you can tell if a person likes to code, by the code that they write.

here's where you are wrong: the person who likes to code intentionally write it in the longest way possible because he loves typing in code so much :3:
