Find the difference

You are given two strings s and t.

String t is generated by random shuffling string s and then add one more letter at a random position.

Return the letter that was added to t.

Example 1:

Description

Given two strings s and t, return true if t is an anagram of s, and false otherwise.

An Anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once.

// Step 1: Deep copy a jagged array with numbers or other arrays in a new array
const originalArray = [2, 4, 10, [12, 4, [100, 99], 4], [3, 2, 99], 0];

const deepCopyArray = (array) => {
  
};
console.log("## deepCopyArray");
console.log(deepCopyArray(originalArray));

// Step 2: Render jagged array in document body using semantic HTML

console.log(countWords("")); // 0
console.log(countWords("            ")); // 0
console.log(countWords("JavaScript !!!   ")); // 1
console.log(countWords("     JavaScript")); // 1
console.log(countWords("    JavaScript is cool      ")); // 3
