   well, maybe start with walking an array or 
list or string, create a stack and also a queue, 
try walking a two- and three-dimensional array 
(what are they used for?). in other words, learn 
standard techniques for working with basic data 
   learn about basic arithmetic and logic 
techniques, too (shifting to multiply or divide 
by two, how to use XOR to filter...). 
   learn about ASCII character codes and sort 
strings by ASCII sort order, learn unicode, 
try sorting unicode strings, change a string 
to all uppercase, to all lowercase.... there 
are lots of techniques for working with strings. 
   as you try stuff out, imagine some real-world 
problem that relates.
