And for all of this I still blunder my way through an exercise to write a function which returns a boolean in response to the question of whether sequence A is a sub-sequence of sequence B. I still draw a blank when asked what the magnitude of complexity is for the

guestsfunction I just wrote (damnit, of course calculating the permutations of a list is n-squared, but this is an interrogation of the random trivia I can manage to recall and I feel like a deer in the headlights). Any shred of confidence I had has been beaten out of me with every mistake, blunder, and rejection.
