No, we invite people from all backgrounds to participate in ACPC! In the past we have had students from other universities and even high schools join us.

No, it is not necessary. You can work alone or in groups of two. However, space will be prioritized for people who already have a teammate. When registering, you have the option to have us pair you with a teammate.

The event will take place on May 4 from 10 am to 4 pm at room 1020 in the Teaching and Learning Complex on the UC Davis campus.

No, participating is completely free! However, you will need to make your own way to the competition site.

Last year we had around 120 participants. We expect more people will participate this year, at around the 150-200 person mark.

Having a strong foundation in high school math and having basic programming skils(loops, conditionals, arrays) is recommended. A good portion of the problems are solvable without needing advanced data structures/algorithms.

Java, C++, C, Python, and much more! See here for more information: https://codeforces.com/blog/entry/79.

We will be using the Codeforces website. At the beginning of the event, we will host a 30-minute practice session which will allow participants to familiarize themselves with the environment.

All details about the contest will be provided during the first 30 minutes of the event.

Each team will have to bring at least one laptop. Please bring a charger. You may bring a notebook, notes, pens, and pencils. We will provide the problems printed out.

A meal will be provided during the contest. Before and after the contest there will be snacks and drinks.

Slots for teams will be filled up on a first-come-first-serve basis, so we suggest registering as soon as possible. If the slots are filled up, you will be placed on the waitlist. We will let you know whether your team's spot is secured or if your team is on the waitlist by April 24th.

Alice and Bob play a game. Alice thinks of two positive integers A and B where A is less than or equal to B. Bob has to report how many integers between A and B, inclusive, are divisible by 10. Help Bob and write a program that solves this question.

Hese is a solution coded in C++:

#include <iostream>

  using namespace std;

  int main() {
  int A, B;
  cin >> A >> B;
  int ret = B / 10 - (A - 1) / 10;
  cout << ret << endl;

  return 0;
  }

We recommend reading Guide to Competitive Programming and solving problems on CSES, as they cover many classical algorithms. You can also setup a Codeforces account in advance and practice solving some of the problems there.
