Isogram

Easy

Instructions

Determine if a word or phrase is an isogram.

An isogram (also known as a "nonpattern word") is a word or phrase without a repeating letter, however spaces and hyphens are allowed to appear multiple times.

Examples of isograms:

  • lumberjacks
  • background
  • downstream
  • six-year-old

The word isograms, however, is not an isogram, because the s repeats.

There is a range of interesting data types in Pharo, it's worth taking the time to browse the hierarchy of class Collection and reading some of the class comments and running some of the examples.
