// Given a positive integer of up to 16 digits, return true if it is a valid credit card number, and false if it is not. Here is the algorithm:

// If there are an even number of digits, double every other digit starting with the first, and if there are an odd number of digits, double every other digit starting with the second. Another way to think about it is, from the right to left, double every other digit starting with the second to last digit.

// 1714 => [1*, 7, 1*, 4] => [2, 7, 2, 4]
// 12345 => [1, 2*, 3, 4*, 5] => [1, 4, 3, 8, 5]
// 891 => [8, 9*, 1] => [8, 18, 1]

// If a resulting doubled number is greater than 9, replace it with either the sum of it's own digits, or 9 subtracted from it.

"""
Copies all keys from the source Redis host to the destination Redis host.
Useful to migrate Redis instances where commands like SLAVEOF and MIGRATE are
restricted (e.g. on Amazon ElastiCache).

The script scans through the keyspace of the given database number and uses
a pipeline of DUMP and RESTORE commands to migrate the keys.

Requires Redis 2.8.0 or higher.

• Regex generated via frak in clojure

• Install clojure and leiningen brew install leiningen

• Create new app lein new app frakproj

• cd into new directory frakproj

• edit project.clj to add [frak "0.1.6"] as dependency. the new file should look like this:

  (defproject frakproj "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://example.com/FIXME"
