Too theoretical and not really an interview prep book. The book is so confusing I dont understand why he has named it “cracking programming interviews”.. None of the explanation make any sense. I got lost after reading 2 pages. It is way too theoretical, The code has no comments and reading the code does not make any sense.I have not read Cormen book for a long time but I have a feeling the theory and questions were taken from Cormen book and just pasted there, which might not be a bad idea except the explanation and code was…
