Eating Black Holes
And we're back with a fresh baked mission straight from the community! So everyone get ready, because we're gonna serve you up something awesome!
"Safe Pawns" Review
Today we will take a look at one of CheckiO's Chess missions "Safe Pawns".
I hope you've heard about the ancient game Chess by now.
In this mission we will take a closer look at the weakest but most numerous
(and maybe even dangerous) chess piece: pawns.
"The Best Number Ever" Review
The mission is simple. Write a function that returns any number. But try to describe why
your number is the best. For example, Sheldon Cooper from The Big Bang Theory thinks that 73 is the best number ever and
he can explain why.
"Verify Anagrams" Review
An anagram is a type of word play, the result of rearranging the letters of a word or phrase to produce a new word or phrase, using all the original letters exactly once. Two words are anagrams to each other if we can get one from another by rearranging the letters.
You are given two words or phrase. Try to verify are they anagrams or not.
"Brackets" Review
Welcome back for another weekly review series!
When you open first "Electronic Station" the first mission that you encounter is the classic
"Brackets" mission. This is a simple, but interesting and useful mission.
"Brackets" can be solved with a wide variety of methods, and CiO players have certainly come up with some clever and ingenious solutions to it.
"I Love Python" Overview
On CheckiO we have all sorts of different and challenging missions. Sometimes you just need to solve inputoutput function.
Sometimes it's a round of codeGolf. Sometimes you will play a game with a special score system.
But two of these missions are very different. These are more creative writing, or as we call them "code essay" missions.
Massive Mission Update + #reviewmycode bonus
Today we would like to announce huge mission roster update and something special for our players! Four new missions are here for you to improve your Python skills
"Feed Pigeons" Review
On our landing page you can find one mission text with solutions.
And this is "Feed Pigeons".
I'm not sure why but this mission can trouble new players.
"Digit Doublets" Review
Did you know that we have the special island in CheckiO that is devoted by Lewis Carroll?
Charles Dodgson (aka Lewis Carroll) was an English writer, mathematician, logician,
Anglican deacon and photographer. He also wrote several books with mathemical and logical puzzles.
"Roman Numerals" Review
The Republic, Julius Caesar, The Colosseum. Yes, I'm talking about Ancient Rome.
A few days ago I read Conn Iggulden's book about Caesar successor, Octavian
and remembered the CheckiO mission "Roman Numerals". So let's look revisit this numeral system.
"Golden Pyramid" Review
Let's look at a classical CS problem that was realised as the Checkio mission.
I mean "Golden Pyramid" mission.
Consider a triangle of numbers. There is one number in the top of the triangle.
On the next level  two numbers, then three and so on.
You are start at the top and should down to the bottom of the triangle.
For each step down you can move to on of two cell below current.
And you "collect" (summarize) passed numbers.
Your goal is find the maximum possible sum of numbers for all possible routes from top to bottom.
