Copy ct_Ex8.html and ct_Ex8.js to new files named ct_Ex9.html and ct_Ex9.js. In this exercise, you translate your flowchart of Ex9 of Part 1 to its equivalent JavaScript code. You need to make changes in your ct_EX9.html including: js script link, header text, and name of the event function digits37(). In the js file of previous exercise, you (should have) separated digits of a number by modulus and division operators. Now, in ct_Ex9.js, you need to make the following changes

Name of the function should be digits37()

Change the output message from its digits to number of 3 or 7s

Implement the function based on your flowchart.

Once you are done, run the program, you should see the following results if you enter 789041 or 5323653345. If not, debug your code.

------flowchart was-----

Devise a flowchart to receive a positive integer number and output how many of its digits are equal to 3 or 7. For instance, if the input is 772, the program should output 2, because there are two 7 there. In another example, if the input is 14367, the program should output 2 as there is a 3 and a 7 in it. Hint, before entering the loop, declare a counter variable and assign 0 to it. Inside the loop, update the counter when necessary. Output the value of the counter variable after the loop.

Hint, you can use if elseif to check conditions, or use logical OR in the condition to make the code more succinct.
