Q1. Do you go by "Chuck" or "Charlie"?
A1. Neither. My friends call me "Charles". You should, too.
A2. The "ei" is pronounced as in "Einstein", like "eye". The esses are soft, like the "s" in "soft". You can pronounce my name as three simple English words: LIE-SIR-SON.
A3. No, but if you are teaching a course based on our textbook, there is an Instructor's Manual written by Tom Cormen, Clara Lee, and Erica Lin, which is available from your local McGraw-Hill representative. This manual contains answers to a selection of problems and exercises, as well as lecture material drawn from courses at MIT and Dartmouth.
