# first-non-repeating-character

## Instructions
|
|
|
|
Write a function that takes a string input, and returns the first character that is not repeated anywhere in the string.
|
|
|
|
For example, if given the input `'stress'`, the function should return `'t'`, since the letter `'t'` only occurs once in the string, and occurs first in the string.
|
|
|
|
If a string contains all repeating characters, it should return an empty string (`""`).
