Task

Emulate a back ATM Machine and its features with a class.

Requirements

Default Settings: new ATM(usersArr) where usersArr is an array of users {username: username, password: password, money: money}

>> atm = new ATM(users<arr)

The class will also have the following methods :

• Register : atm.register(username, password)

  This adds a new user to database with 0$ money, return 0 when done, return 1 when user already exists.

• Login : atm.login(username, password)

  login a user to do action next, return 0 when done, return 1 when wrong username or wrong password are given

• Logout : atm.logout():

  logout current user, return 0 when done, return 1 when user already logged out

• Query Stat : ATM.query()

  query account status, return {money: money} when done, return 1 when user already logged out

• Change Password : ATM.changePass(oldPass, newPass)

  change password, return 0 when done, return 1 when logged out, return 2 when wrong old password is given

• Payment : ATM.pay(count, target)

  Payment to another user registered, return new money when done, return 1 when already logged out, return 2 when no enough money, return 3 when target user not exist

Good luck :-P

Is the bathhouse gender fluid ? ;)

Typo in the description (3 times):

occurence

Second and third sample tests seem to be wrong :

• [(-2, 5), (4, -1), (4, 11), (10, 5)]

  For n = 10: [4, (4, 11)] should equal [4, (4, -1)]

• [(260, 120), (264, 92), (264, 148), (280, 60), (280, 180), (300, 40), (300, 200), (332, 24), (332, 216), (360, 20), (360, 220), (388, 24), (388, 216), (420, 40), (420, 200), (440, 60), (440, 180), (456, 92), (456, 148), (460, 120)]

  For n = 100: [20, (420, 40)] should equal [20, (420, 200)]

• There are many ways to sort an array, you have to be explicit.

• Use katex for math formulas :

  (x – h)^2 + (y – k)^2 = r^2
  

• Description has be rewritten to correspond to actual quality standards.

• In light mode, your example is hard to see.

This one is crazily cool and rewarding. It should be translated to Python by a someone.

f(n) =  \begin{cases} \frac{n}{2} \quad &\text{if }& n \equiv 0 \pmod{2}\\ 3n + 1 \quad &\text{if }& n \equiv 1 \pmod{2} \end{cases} 

I tried to reduce my code for days, not understanding why my formula was wrong!

In the sample tests tester("11000", "01111", 4, 1):

Remove components 1 and 2, price of 1, quality of 4

Isn't it :

Remove component 1, price of 1, quality of 4

To prevent bad understanding, maybe add in the description that indices are 1-based in your sample tests.

Cool, but the output should be a string.

expected false to be true

Is not a very useful message!
