Find the First Non-Repeated Character

Create a function that accepts a string as an argument and returns the first non-repeated character.

Examples

firstNonRepeatedCharacter("g") ➞ "g"

firstNonRepeatedCharacter("it was then the frothy word met the round night") ➞ "a"

firstNonRepeatedCharacter("the quick brown fox jumps then quickly blows air") ➞ "f"

firstNonRepeatedCharacter("hheelloo") ➞ false

firstNonRepeatedCharacter("") ➞ false

Notes

• An empty string should return false.
• If every character repeats, return false.
• Don't worry about case sensitivity or non-alphanumeric characters.
