## pelikan 3 years ago I'm on PS6 Problem 4. I'm having trouble understanding exactly what they are asking for and the pseudo code they have provided. In particular the this part: Let d = {} For every word w in the word list: Let d[(string containing the letters of w in sorted order)] = w . What exactly do they mean by sorted order?

@pelikan what class are you taking? I'm taking MIT 6_00SC and I don't see anything about the problem you describe in PS6 Problem 4. In mine, PS6 is all about programming robots.

Let d = {} For every word w in the word list: Let d[(string containing the letters of w in sorted order)] = w They say this part should be a preprocessing step ... so at the start of the program before you do anything else. Lets assume you have a word list containing the following words: python is pretty powerful first you would Let d = {} so it's empty Then for the first word, which is python Let d[(string containing the letters of w in sorted order)] = w or Let d['hnopty'] = 'python' because (string containing the letters of w in sorted order) = 'hnopty' Then repeat for the rest of the words (because it said for every word in the word list) so you end up with d['hnopty'] = 'python' d['is'] = 'is' d['erptty'] = 'pretty' d['elfopuwr'] = 'powerful'

thanks. I wasn't sure if they meant sorting the words according to the value of each letter or if they just meant alphabetically. Thanks for the clarification!
