Golden Award for Molybdenum 2019 Challenge

It’s been a while since I took my last challenge on Codility and this was the first one I did in 2019. I felt a little bit rusty but it was a great weekend algorithm challenge. I managed to do 100% points on correctness and performance which is awarded with a Golden Award.

The challenge was marked as hard but personally I didn’t felt like it was on the level of the hardest challenges on Codility.Read More »

Golden award for dividing The Kingdom

In the last few months I didn’t have much spare time for writing posts on this blog or maybe I was just being lazy. But that doesn’t mean that nothing interesting was happening during this period. So the next few post will be some “retro” stuff from the previous months and I think deserve to be published here. This post will be about the “Digital Gold” Codility challenge.

DivideTheKingdom

I got a “Golden Award” for this solution so here are the details about the challenge task:

An old king wants to divide his kingdom between his two sons. He is well known for his justness and wisdom, and he plans to make a good use of both of these attributes while dividing his kingdom.Read More »

Using free theater tickets can be such a tough decision – this algorithm is here to tell you how many different options you have

Kate is a girl that was given  a very nice birthday gift – three theater tickets. She can pick three performances in the next N days that she would like to attend.  On the program, performances are named by integers. Every day, one performance is staged. Kate wants to choose three days (not necessarily consecutive) to go to the theater.

In how many ways can she use her tickets?

Briefly that was the task in the Zinc 2018 Challenge on the Codility platform, sixth challenge that was published this year and sixth Golden Award for my solution.Read More »

A story about a real struggle with an algorithm

I don’t have that much of a free time but from the one I have I try to make the most of it, and I think that is very important to have quality hobbies. For some people that is crossword puzzles, for some is reading books, for me that is running and from this year I’m taking participation in Codility Coding Challenges as well.

In this post I would like to share my experience with the latest Codility challenge – Cuprum 2018. Read More »

Four In A Row – Golden Award For Cutting Complexity Challenge

Another Codility Challenge is out there, this one is called “Cutting Complexity Challenge” and it’s the fourth that is published this year. The same as the previous three, my solution was awarded with “Golden Award“. What is different about this challenge is that was sponsored by ASML company that is the world’s leading manufacturer of chip making equipment and there are some nice prizes for the best solutions that will be announced after the challenge is over.

Golden Hat-Trick, another Award for my Nickel 2018 solution

This was the third Codility Challenge this year and for the third time I’m getting Golden Award for my solution. After the Ferrum 2018 and Cobaltum 2018, this award is for the current challenge Nickel 2018. This time I got the solution in my head as soon as I read the assignment and I was doing that while holding a screaming baby in my hand and my 2-year old was destroying the living room in the background. With this task I felt like I wasn’t challenged properly.

Also I didn’t need to solve this in Visual Studio which is the environment that I’m used to and I use to solve these challenges.
