You must submit a file called, called pass.js
pass.js: Validator of passwords
Your task this week will be to program a valid password validator.
A password is safe only if it satisfies the following constraints:
- It has from 5 to 10 characters (inclusive)
- It contains at least one lowercase letter, at least one capital
letter and at least one number
- The first character is different from the last
Once the password is entered and validated, the user is asked to copy it again to validate.
Course of the program
More precisely :
1. Ask the user to enter a password with:
prompt ("Please choose a password");
2. Check if the password matches the requirements
2a. If the password is invalid, display "Invalid password" and end the program (the rest of the program runs only if this step was done correctly)
2b. If the password is correct, go to step 3
3. Ask the user to enter the password again with:
prompt ("Please enter the password a second time to confirm");
4. Check if both passwords are the same
4a. If the passwords do not match, show "You
did not enter the same password twice" and ask to start again
4b. If the two entered passwords match, go to
step 5
5. Once the password is valid and entered twice correctly, display "Password saved!"
Here is an example of the execution of the program :
Please choose a password
> the user enters "abc"
Invalid password
Another example :
Please choose a password
> the user enters "l33th4xx0r"
Please enter the password a second time to
confirm
> the user enters "abc"
You have not entered the same password twice
Please enter the password a second time to confirm
> the user enters "l33th4xx0r"
Password saved!
Your program must be complete, with comments that
indicate the name of the file, the author (your name), a
brief
description of the usefulness of the program. There must also
be
comments that explain what each variable corresponds to,
and the operation of the program. Use statements of
appropriate loop, correct indentation, and block statements
in the body of if and loops. Your program should avoid
redundant and repetitive calculations.

For a closed economy – i.e. an economy in which there are no international transactions – GDP is $12 trillion, consumption is $7 trillion, taxes are $3 trillion, and the government runs a deficit of $1 trillion. (Assume transfer payments are zero.)
a) It follows that private saving is ________.
b) National saving is __________.

Design a circuit that takes two strings of binary digits and outputs 1 (True) if the strings “partially” match, and 0 otherwise. To keep this manageable assume the two strings are three bits long, that is a1a2a3 and b1b2b3 where each ai or bi is a one or a zero. The strings are a perfect match if for all i, ai = bi;. The strings are a partial match if at most one i, ai is not equal to bi. A perfect match can be considered a partial match.

TotsPoses, Inc., a profit-maximizing business, is the only
photography business in town that specializes in portraits of small
children. George, who owns and runs TotsPoses, expects to encounter
an average of eight customers per day, each with a reservation
price shown in the following table. Assume George has no fixed
costs, and his cost of producing each portrait is $25.
| Customer | Reservation price ($ per photo) |
| 1 | 50 |
| 2 | 46 |
| 3 | 42 |
| 4 | 38 |
| 5 | 34 |
| 6 | 30 |
| 7 | 26 |
| 8 | 22 |
a. Suppose George is permitted to charge two
prices. He knows that customers with a reservation price above $30
never bother with coupons, whereas those with a reservation price
of $30 or less always use them. At what level should George set the
list price of a portrait? At what level should he set the discount
price? How many photo portraits will he sell at each price?
List price of a portrait: $__
Number of portraits to be sold at the list price: __portraits
Discount price of a portrait: $__
Number of portraits to be sold at the discounted price:
__portraits
b. In this case, what is George’s economic
profit and how much consumer surplus is generated each day?
Economic profit: $__
Consumer surplus: $__

Wilson Publishing Company produces books for the retail market. Demand for a current book is expected to occur at a constant annual rate of 7,300 copies. The cost of one copy of the book is $14. The holding cost is based on an 17% annual rate, and production setup costs are $160 per setup. The equipment on which the book is produced has an annual production volume of 20,500 copies. Wilson has 250 working days per year, and the lead time for a production run is 17 days. Use the production lot size model to compute the following values:
