First of all... Apologies if I'm not posting this in the right forum.

Can anyone please recommend me any book for Data Structure and Algorithm? Which one did you personally like? Please consider that my intent to study DSA is only focused on technical job interviews.

The book "Introduction to Algorithm by Cormen" seems to be the popular one. But in the reviews section people have criticized the book over too much of complex maths involved, difficulty to understand the content, lack of explanations given, and the bulky size.

Complex numbers are rarely used in analysis of algorithms, in fact most of it is done using integers and some fractions, so the irrational numbers are rarely used.

Or did you mean hard? Most of the math used in analysis of algorithms is calculus (limits) and some work with infinite series. Its solidly college level math. If you didn't do well in other college level math, you're not going to be happy.

When I was in grad school, we used Sarah Baase's Computer Algorithms: Introduction to Design and Analysis, third edition, co-authored with Allen Van Gelder, Addison-Wesley, 2000.
