+# [[2017-03-08] Challenge #305 [Intermediate] The Best Conjunction](https://www.reddit.com/r/dailyprogrammer/comments/5yaiin/20170308_challenge_305_intermediate_the_best/)
+
+## Description
+
+Your job is to find the best conjunction—that is, find the word with the most
+sub-words inside of it given a list of English words. Some example include:
+
+* Something (3 words: So, me, thing)
+* Awesomeness (3 words: awe, some, ness)
+
+## Formal Inputs & Outputs
+
+### Input description
+
+Use a [list of English words](http://www-personal.umich.edu/~jlawler/wordlist)
+and a *minimum sub-word length* (the smallest length of a sub-word in a
+conjuncted word) to find the *best conjunction* (most sub-words) in the
+dictionary!
+
+### Output description
+
+    minSize 3: disproportionateness (6: dis, pro, port, ion, ate, ness)
+    minSize 4: dishonorableness (4: dish, onor, able, ness)
+
+Find minSize 5
+
+## Notes/Hints
+
+* Be aware the file is split by `\r\n` instead of `\n`, and has some empty
+  lines at the end
+* In order to run in a reasonable amount of time, you will need an O(1) way of
+  checking if a word exists. (Hint: It won't be O(1) memory)
+* Make sure you're checking all possibilities—that is, given the word *sotto*,
+  if you begin with *so*, you will find that there is no word or combination of
+  words to create *tto*. You must continue the search in order to get the
+  conjunction of *sot* and *to*.
+
+## Bonus
+
+* Each sub-word must include the last letter of the previous subword. For
+  example *counterrevolutionary* would become *count*, *terre*, *evolution*,
+  *nary*
+* Instead of simply the last letter, allow any number of letters to be shared
+  between words (e.g. *consciencestricken* -> *conscience*, *sciences*,
+  *stricken*)
