HOW TO FORMAT PSEUDO CODE 

Make sure you:
- specify the input and output parameters
- declare and initialize all the variables used.
- do not declare or initialize variables you do *not* use.

Typesetting,  write the name of
- functions and procedures in small caps font {\sc Function-Name}
- data structures in emphasized font {\em data-structure-name}
- constants in courier font {\tt Constant-Name}

- For making an assignment, use the form "a <-- b"  ($a \leftarrow b$)
- For making a test, use the form "a = b"
- For control constructs, limit yourself to the minimum: while,
  repeat, for, etc..  Do not use when, unless (they are Lisp'y and
  not conventional).

- Use an algorithm style package, avoid formatting yourself.

- Make sure you provide a worst-case complexity estimate in the text.
