TWC 149: Limited Fibs, and Bases of Unusual Size

(Currently editing)

In which we see that you don't need all the Fibs, and have trouble turning 21.

TWC Task #1 - Fibonacci Digit Sum

Given an input $N, generate the first $N numbers for which the sum of their digits is a Fibonacci number.

(i.e. Generate OEIS A028840)





TWC Task #2 - Largest Square

(i.e. Generate OEIS A287298)

Given a number base, derive the largest perfect square with no repeated digits and return it as a string. (For base>10, use ‘A’..‘Z’.)





TWC 148: Numbrs, and Cubic Cards

In which we see that you can spell "numbers" without an e, and realize that first implies an ordering.

TWC 147: Prime without Left, and Pent without Quad

In which we bravely overcome ambiguity, and dodge two approaches in the face of (O³).

TWC 146: 10K Prime and CW Trees (redirect)

TWC 146: 10K Prime and CW Trees

In which we leap tall primes in a single bound, mis-take a tree, test percussion, and find the limits of a Curious Module.

Task 1: 10001st Prime Number - One-liners (expanded) in Raku and Perl.

Task 2: Curious Fraction Tree - Solutions in Raku and Perl (with 200+ tests), and another Perl solution using a CPAN module.
