Introduction to algorithms for a student?

Question

Algorithms

Please help a ninth-grader to learn algorithms (data structures) and take the first steps in the Olympiad programming. There is a C ++ base, which, I hope, is enough for such cases - I studied for a month according to Laforet. I tried on my own - I searched here and on other resources, but it turned out that Sedgwick (Fundamental Algorithms in C ++), which I chose, is not easy for me - the calculation for the audience is stronger and the presence of ugly mathematics from high school. An excellent Olympian with great motivation (1K+ pages won't bother you), but without a "spiritual mentor", so great forums like this one are my last chance to get into programming. What do you advise me to do? Stop whining and take on Sedgwick, or are there better books? Sites, collections of tasks? I would be very grateful for any link or comment. PS

Answer 1

My advice: stop whining and take on Sedgwick. Everything is not so difficult to explain there, on the contrary, it is relatively simple.

Answer 2

Wirth's book ("Algorithms and Data Structures") for a start I propose to master.

Answer 3

Olympiad programming courses 1C - there are also distance courses, a free blog on pedsovet.org mathematical models in computer science
