## Raku challenge Week 3

## Raku challenges Week 2

## Raku Challenge Week 1

## Combinations in Raku

Monday morning, and there are new tasks in the new weekly challenge 067. Both of them require similar Raku tools, namely, the cross operator X.

## 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.

## Practicing Raku challenges

## 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

## Raku daily skill builders

Here is my Raku solution of the Task 1 on Week 65. The task is to print all $n-digit numbers, whose sum of digits is $s.

## 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.

Task 1. Remove leading zeros from positive numbers.

Task 2. Convert a number to the one represented as a base-35 number and back.

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.

A few Raku challenges solutions: printing arrays, generating Leonardo numbers, converting to octals.

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.
