Trick Two

1. Check if a string is well formed (special case: ignore within quotes) e.g.

    (...[...{...}...]...)      <- Well formed
    (...[...{...]...}...       <- Malformed
    (..."[...{...]...}"...)    <- Well formed (Special case)  

2. Count anagrams in a list of strings e.g.

    cat,far,act,car,arc,rac     <- 5 anagrams
