Task 1: Binary Prefix

Submitted by: Mohammad Sajid Anwar

You are given a binary array.

Write a script to return an array of booleans where the partial binary number up to that point is prime.

Example 1

Input: @binary = (1, 0, 1)
Output: (false, true, true)

Sub-arrays (base-10):
(1): 1 - not prime
(1, 0): 2 - prime
(1, 0, 1): 5 - prime

Example 2

Input: @binary = (1, 1, 0)
Output: (false, true, false)

Sub-arrays (base-10):
(1): 1 - not prime
(1, 1): 3 - prime
(1, 1, 0): 6 - not prime

Example 3

Input: @binary = (1, 1, 1, 1, 0, 1, 0, 0, 0, 0, 1, 0, 1, 0, 0, 1, 0, 0, 0, 1)
Output: (false, true, true, false, false, true, false, false, false, false, false, false, false, false, false, false, false, false, false, true)

Output: ("raku", "python", "perl")

Example 2

Input: @words = ("the", "weekly", "challenge")
       @alien = qw/c o r l d a b t e f g h i j k m n p q s w u v x y z/
Output: ("challenge", "the", "weekly")
