Problem: Given a list (array) of words, find all the possible anigrams in that list and return
a two deminitional array of the results.
Assumption: all the strings are valid words.
###
anagrams = (words) ->
# Store as a map for each words.
anagrams = {}
# Create a new array of the sorted strings to use as the key in the array
sorted = words.map (word) ->
return word.split('').sort().join('')
sorted.forEach((st, i) ->
if (!anagrams.hasOwnProperty(st))
anagrams[st] = [words[i]]
else
anagrams[st].push(words[i])
)
results = []
for key, value of anagrams
results.push value if value.length > 1
return results
testWords = ['dell', 'ledl', 'abc', 'cba', 'will', 'not', 'match', 'these']
console.log(anagrams(testWords))
