“Uehara’s First course in algorithms through puzzles is an immensely gratifying book to read. It is a neat and short introduction to algorithms, which manages to combine fun with depth. … This reviewer is thinking of employing Uehara's book as recommended reading.” (Michael Soltys, Mathematical Reviews, May, 2020)“This is a first course in computer-science algorithms, aimed at undergraduates. … The puzzle parts are the best part of the book. They are concrete, well-explained, and well-motivated, as well as being rigorous computer science.” (Allen Stenger, MAA Reviews, April 22, 2019)
