Raku Challenge Week 1

Task 1. Capitalise all small letters ‘e’ and count the number of replacements in the string ‘Perl Weekly Challenge.’

Task 2. Write a one-liner that, for the numbers from 1 to 20, prints ‘fizz’ if the number is divisible by 3 and ‘buzz’ if it is divisible by 5.

Collatz Conjecture in Raku

An interesting task offered on Week 54 of the Perl Weekly Challenge: Print the Collatz Conjecture for the given integer number. The conjecture is that for any starting number, the sequence ends with 1.

More Raku challenges

Task 1: Find the first 20 so-called Gapful numbers. Task 2: Print all palindromic ddmmyyyy dates between 2000 and 3000. Task 3: Find the first multiple of the given number, which only contains digits 0 and 1.

Programming challenge: insert signs between digits

Here’s another drill offered by the Perl Weekly Challenge on Week 44. The task is to get a string 123456789 and insert the signs + and – between the digits so that the evaluated value of the new string equals 100.

On Perl 7

A couple of days ago, Perl 7 was announced.

Isn’t that a great news? Well, yes and no. I have my personal feelings about this but I hope I can also see some other things that are not so much subjective.

Check if the number can be represented as a power of integers

In the second task of this week’s Challenge, you have to find two integers that being powered as xy, give the requested integer number n.

Raku string vs integer practices

Hey there, there’s another task #066-1 offered by the Perl Weekly Challenge (why still not mentioning Raku in the name?).

Integer-divide the two given integers, $m and $n, without using multiplication, or division, or modulo.

Another Raku one-liner

Let me demonstrate another interesting one-liner that I find to be a good addition to my last years’s book Raku One-Liners. The task was inspired by this week’s problem from the Perl Weekly Challenge.

Some tips for working with hashes in Raku

In this blog post, I am giving a number of examples of how you can use hashes in the Raku programming language in a correct and incorrect ways and explain how to avoid the chance to mislead yourself.

Chapter 11. Control Flow

In this chapter, we are implementing the if and else keywords, and are approaching the more complex structures such as loops. After introducing the AST earlier, these tasks become quite doable. Also in this chapter: code blocks are introduced.

Chapter 10. Test suite

The compiler becomes bigger and bigger, and we are going to add more syntax to the Lingua language. It is a good time to make a pause in the compiler development and ensure some stability. In this chapter, we will create a test suite, which will allow us to find problems in the implementation and prevent new bugs when extending the language.

Chapter 9. Evaluating AST

In this chapter, we traverse the AST that was built earlier and create the methods to evaluate (or execute) the nodes according to their meaning. Another interesting feature of Raku, the so called getters, is used in the code.
