Series Details

About

We'll go over one algorithm every session, although more sessions may be needed for an algorithm depending on the collective understanding of and confidence in that algorithm. I'm going to be programming in C++, but if you are familiar with Java or Python, you can still use that language, as a) C++ is very similar to those languages and b) I'm going to cover algorithms in a visual manner mostly, so there won't be too much programming; we will be programming only when implementing the algorithms.

Tutor Qualifications

I have been programming in C++ for 2.5 years, and competitively programming for about a year. I have experience with competitive programming competitions such as the American Computer Science League (ACSL), the United States of America Computing Olympiad (USACO), and some Codeforces contests. During the 2022-2023 USACO Contests, I passed the Bronze Division with a perfect score and got some Silver Division problems partially right, so I view myself well acquainted with fundamental algorithms like binary search, DFS (depth-first search), BFS (breadth-first search), and more. I'm excited to teach learners how to think algorithmically when solving problems and implement these algorithms to code.

✋ ATTENDANCE POLICY

Learners should have prior knowledge of C++, Java, or Python. If you were a member of my previous C++ Bootcamp series in Schoolhouse, you'll be proficient to join as well, as the series, as I mentioned in the orientation, can be considered a prerequisite for this series.

I expect learners to join every session, and 2 unexcused absences will result in withdrawals. I may host occasional office hours, but there will be no catchup sessions. Office hours will be used to help with the optional practice problems I will be giving out at the end of every session, not to help catch up on what learners missed.

About the Tutor

Hi, I'm Jimmy! I'm a junior in high school interested in learning and teaching math and computer science I also teach SAT Bootcamps and other enrichment topics. In my free time, I like to play sports like running and soccer, watch movies (love Nolan films), and read classic books (Dostoyevsky is my favorite). I look forward to teaching you!

Session 6

Computer Science

- Advanced Sorting with Structures We'll learn advanced sorting methods with structures in C++. Note: It may be a little difficult for learners with a background in Java and Python to implement this, as the methods and syntaxes are different. Follow along as much as you can. This is not something essential for competitive programming, so don't worry.

Other Topics

- Optional Meetup This is an optional meetup for some Q/A and advice for further learning and progressing in competitive programming. I'll share some good resources for learning competitive programming and solving competitive programming problems. I'll also share some competitive programming competitions that are both challenging and exciting.
