The Two Pointers technique is a strategy commonly used in computer science and programming for solving problems involving arrays or sequences. It involves using two pointers that traverse the array or sequence from different positions, often moving in opposite directions or at different speeds. This technique is particularly useful for solving problems related to searching, optimization, or manipulation of arrays efficiently.

A sequence of integers is given. Find the number of integers in the sequence and their sum.

A store offers an assortment of toys of various types. For each type, the number of toys and the price of one toy are known. Determine the total number of toys with a price less than $50$ hryvnias.

Hello everybody! My name is Sergey Kolodyazhnyy and I am one of the co-founders of the Eolymp. Today I would like to share with you the story of how my computer science teacher Zhukovsky Serhiy (@zss) and I created one of the largest Ukrainian sites for studying computer science. Of course, over the years, many caring people have helped the site. This post mentions only a few of them, but I am very grateful to everyone who contributed.

Recently, information has been spreading on the internet about our company's ties with the russian federation. We officially state: our company has no ties with the russian federation and does not cooperate with russian or pro-russian companies or websites.

You may have noticed some changes on our site today, specifically some new colors and changes on the profile page. We've introduced a system that assigns titles to users based on their performance in rated competitions like the Eolymp Cup and Weekend Practice. These titles help organize users into groups according to their performance and provide a bit of motivation to solve more problems.

Hi Eolymp Community!

A number is called massive if it can be written in the form $a^n$, that is, $a$ raised to the power of $n$.

Solve the quadratic equation $a\cdot x^2+b\cdot x+c=0(a\ne 0)$.

You are going to toast some slices of bread for an upcoming party. You have a frying pan that can hold at most $k$ toasts at the same time. Toasting one side of a toast takes $2$ minutes.

Given $n$ balls. Among them, $n-1$ have the same weight, and one ball is heavier than the others. Determine the minimum number of weighings on a two-pan balance (without weights) required to find the heavy ball.

Today we'll take a look at how Eolymp tests submissions: what happens after you submit a solution,how it is executed, how the results are verified and what outcomes there are. Hope this article will help you betterunderstand how the system works and make it easier to work with it.
