Example 1 The most classical … Continue reading “ 10/25. Reduction operator in Perl 6”
9/25. More on X, .., and … in Perl 6
Welcome to Day 9 of the Perl 6 One-Liner Advent Calendar! On Day 6, we had a construct with a cross-operator, (999…100) X* (999…100). Today, we’ll dive into a similar construction from November: 1..10 X* 1..10 It prints the items of the product table for the numbers from 1 to 10: (1 2 3 4 … Continue reading “ 9/25.

Today, we are solving problem 2 from Project Euler. The task is to find the sum of all even Fibonacci numbers below four … Continue reading “ 8/25. Adding up even Fibonacci numbers in Perl 6”
7/25. The joy of Unicode in Perl 6
Welcome to Day 7 of the Perl 6 One-Liner Advent Calendar! Today, we’ll look at the month of March in the Perl 6 Calendar 2019: The code here is using three characters outside of the ASCII land.
