You wrote that you're going for coding interviews, so I'll focus on various aspects that will be looked at by interviewers rather than pieces of code which other respondents already have. Through hands-on projects, students gain exposure to the theory behind graph search algorithms, classification, optimization, reinforcement learning, and other . Ratiorg got statues of different sizes as a present from CodeMaster for his birthday, each statue having an non-negative integer size. You could just use 2D slicing (see the corresponding stackoverflow topic) and do. This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below.

Since he likes to make things perfect, he wants to arrange them from smallest to largest so that each statue will be bigger than the previous one exactly by 1. You can't just call it and check its result value in a test, for example, you actually have to capture the output from the terminal. Why not create a constant value such as MARGIN for it? You cannot let this ruin your reputation, so you want to apply box blur algorithm to the photo to hide its content. A set of values that can be assigned to the variables. Before creating the game logic, we need to design the basic layout of the game. In fact, it should probably be Cell's __str__ method instead. The link to the post with the source code. To review, open the file in an editor that reveals hidden Unicode characters. // Strings can be rearranged in the following way: "aa", "ab", "bb". Read on for a walkthrough of how the code works. Let's define digit degree of some positive integer as the number of times we need to replace this number with the sum of its digits until we get to a one digit number. .strip(): Normally .strip() is chained at the end of a string where the data can have extraneous spacing, but this one is your own string. You might also get some constant-factor time wins by iterating over the lists with enumerate instead of doing the for index in range() thing, and minimizing the number of extra variables you allocate.

It could access Cell objects and -- when passed slices --- could even return an iterable over the Cells. Collection of coding challenges from CodeSignal. Instead of looping unnecessarily over out-of-bound cells, try instead adjusting the range boundaries: This is just a spur-of-the-moment idea, but you could implement __getitem__ for the MineBoard class. Each year the balance increases by the rate percent of the current sum. Thanks Felicity for your post.

Determine how many pieces of candy will be eaten by all the children together. A ticket number is considered lucky if the sum of the first half of the digits is equal to the sum of the second half. This allows you to make various MineBoard methods less complex, for example: In all other places, you use row and column indexing, but in this method you're using an index.

Run code live in your browser. Classes exposing private attributes as public: Proper OOP ensures that the internals of how classes achieve their magic are hidden. There is a requirement to check for completion of the game, each time a move is made. Generally the code shows a consistent style, so in that regard I think it looks good.
