contamination_string.js

// Description:
// An AI has infected a text with a character!!
// This text is now fully mutated to this character.
// Starting with the original text, and given a character, return the text once it has been mutated so that all of the characters in the original text have been replaced with the character.
// If the text or the character are empty, return an empty string.
// There will never be a case when both are empty as nothing is going on!!
// Note: The character is a string of length 1 or an empty string.

// SOLUTION:

const contamination = (text, char) => char.repeat(text.length);
