***** Answer to question 3 ***** 


//Define function name
function areTheyEqual(arrayOfNumbers) {
  //Start with the first index, continue and end after the last index
  for (let i=0; i < arrayOfNumbers.length; i++) {
    //Step 1: areTheyEqual = 0
    //Step 2: Take a number assign it areTheyEqual
    let numberOne = arrayOfNumbers[i];
    //Step 3: Take next number and check if it's equal to areTheyEqual
    //Step 3a: Check if the next number exists 
    //Step 4: If yes, repeat Step 3 until there are no more numbers
    //Step 5: If no, produce false, and exit the loop
    let numberTwo = arrayOfNumbers[i+1];
      if (numberOne !== numberTwo && numberTwo !== undefined) {
        return false;
        }
    //Step 6: Produce true after the loop 
  }
  return true;
}



*****  Answer to question 4 ***** 
function doesFiveAppearAtLeastTwice(arrayOfNumbers) {
  //Step 1: Set/Start numberOfFives with 0
  let numberOfFives = 0;
  //Step 2: Start with the first index, continue and end after the last index
  for (let i=0; i < arrayOfNumbers.length; i++) {
    if (arrayOfNumbers[i] === 5) {
    //Step 3: If a 5 exists, increment numberOfFives
    numberOfFives++;
    }
    }
    //Step 4: If 5 exists at least twice, return true
    if (numberOfFives >= 2) {
      return true;
    }
    return false;
