На жаль через технічні несправності наш гугл екаунт було заблоковано. Але ми уже працюємо над вирішенням цієї ситуаціі і повернемось до вас у п’ятницю із новою порцією цікавої інформації. Зовсім скоро ми опублікуємо додаткове оголошення.

“Developers over-optimise for the ergonomics of typing and not enough for the ergonomics of thinking. “🤔 says the author of today’s article and provides a list of other activities of effective software development. What do you think? https://daniel.fone.net.nz/blog/2020/10/21/talking-typing-thinking-software-is-not-a-desk-job/

Привіт, друзі,
 
Ми обіцяли вам провести другу частину івенту сьогодні, проте наш YouTube-канал ще в процесі відновлення.
 
Поки питання вирішується, ми зробимо запис всіх доповідей. Як тільки канал буде знову живий, ми опублікуємо відео та повідомимо вам тут.
 
Якщо маєте питання, побажання чи критику – пишіть у коментах 😉

​​JavaScript turned 25 🥳 Look at this amazing visualisation of its development!

Друзі, в нас прекрасні новини. Ми знову в строю з нашим ютуб каналом! 🥳

Запис JS Meetup is Coming доступний на каналі. Як і обіцяли, ми вже готуємо записи двох інших доповідей, що не відбулись через технічні проблеми, а саме:

⁃ Чому реактивне програмування вимагає іншого підходу до мислення?
⁃ Progressive Web App і чому вони такі прогресивні

Також, скоро ми проведемо кодінг доджо, реєстрація буде відкрита уже завтра 😉

Підписуйся і став дзвіночок – https://www.youtube.com/channel/UCY82a2l4__P1F2QvLPbwnmA

Привіт, друзі!

Як ми і обіцяли анонос кодінг dojo!

Ви коли-небуть грали в Тетріс, а може ви й зараз є фаном цієї гри? Тоді у нас для тебе чудові новини!


Ми перенесли тетріс у веб і у тебе є можливість зіграти в гру, але не просто натискаючи стрілочки, а написати власний алгоритм! 😌

Долучайся до нашого нового кодінг dojo івенту “Think you can Tetris?”. Клич друзів та покажи хто тут гуру тетріса і алгоритмів! 🏆 Найкращим обіцяємо подарунки, а лінивим - стрім івенту. 😆

Коли? Стартуємо 17 грудня о 13:00. Закінчуємо 18 грудня о 17:00.

​​Time for our JS QUIZ in December!

Quiz rules:
1) Try to solve task below, write the program code in your repo and add comment with link to this post;
2) The first two players with intresting and optimal solutions will receive wonderful presents!
3) Our game is limited in time, we are going to wait for your answers till Monday (14th of December 2020).

Task will be in next post👇🏻

JS QUIZ TASK😍:
Every year Santa Claus faces a more and more difficult task. The number of children in the world is increasing rapidly, while Santa's old patched up sack can only accommodate a few presents at a time. And every child wants their own very special present... This means that, ever so often, once his sack is partially or completely empty, Santa has to fly back to his base in Lapland to replenish his supplies. So irksome has this become that Santa has decided to resort to modern operational research to aid him in his sack-packing and route planning. Please write a program which will guide Santa through his daily chores.

Input
The input starts with a line containing a single integer t<=100, the number of test cases. t test cases follow.

The first line of every test case consists of four integers n x y S, denoting the number of good children who will receive a present from Santa, the x and y coordinates of Santa's home base, and the amount of space in the sack, respectively (1<=n<=10000, -10000<=x,y<=10000, 1<=S<=100000). n lines follow, each consisting of three integers xi yi si - the x and y coordinates of the i-th child's home, and the amount of space taken up by this child's present when in Santa's sack, respectively (-10000<=xi,yi<=10000, 1<=si<=S).

Output
For each test case output a sequence of space separated integers, corresponding to successive actions that should be taken by Santa:

-i (1<=i<=n) signifies that Santa should travel to his base and pack the present for the i-th child into his sack (he needs to have sufficient room in his sack to do this).
i (1<=i<=n) signifies that Santa should travel to the i-th child's home and leave a present for him/her.
0 signifies that Santa should travel back to his base and end his Christmas activity (and that you want to proceed to the next test case).
Assume that Santa starts in his base and always travels between points by the shortest possible route (along straight lines). All distances are measured using the Euclidean metric.

Score
The score awarded to your program is the total of all scores obtained for its individual test cases. The score for a test case is calculated as I/P, where P stands for the distance covered by Santa in your solution, while I is a test case specific constant (I= n*d+D*(s1+...+sn)/S; d is the mean distance between two homes, while D is the mean distance between Santa's base and a child's home for the given test case).

No points are awarded for incompletely solved test cases (when not all the children receive presents). Any other violation of transport rules results in Wrong Answer.

Example
Input:
1
3 0 0 3
1 0 1
1 0 2
1 0 3

Output:
-1 -2 1 2 -3 3 0

Score:
2/(1+1+1+1)= 0.5

Good luck🤩!
