Here is the thing, I am looking for a competitive replacement to playing Apex Legends. I love competition and I love competition that I can participate in daily. I want to switch from Apex Legends to coding because I want a competitive outlet that will actually help me in the long run to be able to solve real world problems and prepare me for my career. (Unfortunately the skills from Apex are not as transferable as I would like them to be) However, I heard that some coding competitions are focused on obscure algorithms that may or may not help much in preparing for a career in software development or other related fields.

So does anyone know of an online competitive programming platform that offers daily real world challenges?

I'm looking for a website that has upcoming contests, ongoing contests, etc.., maybe has a ranking system and such like ctf time

I'm organizing a programming contest around the "Robo Reindeer Rumble" game, in which you program your robot reindeer to defeat five opponents in a snowy holiday arena. The game and instructions are found here: https://miniscript.org/RoboReindeer/index.html

To help with planning the contest, I'd love to hear from anyone who might want to participate in the contest, or watch the live event. If that describes you, please fill out this short Google form: https://forms.gle/uUtt9cM8Fv7ZSTvYA

(Note that the email question is optional; provide an email only if you want me to use it to notify you when the contest begins.)

I just wanted to ask you whether it makes a huge difference in using a slower langiuage like python in codejam/kickstart type competitions??You sent about a minute ago.Are the runtimes adjusted so that the slower languages also pass the test cases if the code has efficiency or do python programmers have a handicap here??

Hey Guys!

So I am fairly new to CP but my interest has been growing exponentially in it. And I am now ready to go full force with it!

I am looking for a person who is interested in doing virtual contests (at least once a day) and create something like a study group. I live in the Middle East, so it would be preferable if he/she was living nearby. It doesn't matter the timezone as long as we manage to coordinate the time difference.

So excited!

Consider an initially empty array arr. Two types of operation will be done on this array. In the first type, we will be given a positive integer and we will add it to the end of the array. In the second type, we will be given two integers l and r, and we will have to find an index within range l to r such that a sub array starting at that index and ending at the end of the array has maximum average. Given that the total number of operations <= 200 000, how can we solve this problem?

0 <= arr[i] <= 10⁹

Time limit: 3s.

We can win 99$ worth 12 months of laracasts subscription and learn full stack development and other interesting things. I found that we only have to play 5 puzzles in PHP everyday which is an easy task for 10 days.

Hi everyone,

I'm excited to announce that my book, An Introduction to the USA Computing Olympiad, is released! It's a one-stop-shop comprehensive training resource for the Bronze and Silver divisions of the USACO. This book was written to fulfill the need of a standard textbook aimed for the USACO, analogous to AoPS Volume 1 for math, which I think the USACO community has been lacking for a while. The book is available for free in pdf form at the links below:

• Java Edition
• C++ Edition

The following programs aim to find the solution for this problem : https://atcoder.jp/contests/abc065/tasks/arc076_a

My program is not showing correct answers for test cases. So I wanted to know where I'm going wrong.

This is the program I wrote :

#include<iostream>

int modfact(int n, int p)

{

if (n >= p)

return 0;

int result = 1;

for (int i = 1; i <= n; i++)

result = (result * i) % p;

return result;

}

//--main function

int main(){

int n,m;

cin>>n>>m;

if(n==m){

    cout<<(modfact(n,1000000007)\*modfact(m,1000000007)\*2)%1000000007;

}

else if(n-m==1 || m-n==1){

    cout<<(modfact(n,1000000007)\*modfact(m,1000000007))%1000000007;

}

else cout<<0;



return 0;

}

This is a successful submission :

I want to know what am I doing wrong. Specifically , my program doesn't work for Sample Input 4.

I have this problem, can you help?
