Write a defining table and a JavaScript program that computes and outputs the rate of change of a price. The program must allow the user to enter a previous price and a current price. The formula for the rate of change is

rateOfChange =  currPrice - prevPrice

prevPrice

Your program should allow a user to enter real numbers such as 7.54. If you wish, you may use the following HTML code in your program.

<!DOCTYPE HTML>
<html lang="en-us">
<head>
<meta charset="utf-8">
<title>Rate of Change</title>
<script>

// Your JavaScript function belongs here.

</script>
</head>

<body>
    <h1>Rate of Change</h1>
    Previous Price <input type="text" id="prevPrice"><br>
    Current Price <input type="text" id="currPrice"><br>
    <button type="button" onclick="computeRateOfChange()">Rate of Change</button><br>
    Rate of Change <div id="rate"></div>
</body>
</html>

Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2 Note: The above algorithm outputs the 0's and 1's in reverse order.
