# Isogram
|
|
|
|
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.
|
|
|
|
Examples of isograms:
|
|
|
|
- lumberjacks
|
|
- background
|
|
- downstream
|
|
|
|
The word *isograms*, however, is not an isogram, because the s repeats.
