Table of Contents

Problem Statement

Considering in order of length, n, all sequences of consecutive primes, p, from 2 onwards, where p < 1000 and n>0, select those sequences whose sum is prime, and for these display the length of the sequence, the last item in the sequence, and the sum.

Let's start with the solution:

Source code in the raku programming language

use Lingua::EN::Numbers;

my @primes    = grep *.is-prime, ^Inf;
my @primesums = [\+] @primes;
say "{.elems} cumulative prime sums:\n",
    .map( -> $p {
        sprintf "The sum of the first %3d (up to {@primes[$p]}) is prime: %s",
        1 + $p, comma @primesums[$p]
      }
    ).join("\n")
    given grep { @primesums[$_].is-prime }, ^1000;
