1. Train Ticket: Write a program that reads a person’s age, then computes and displays the price the person needs to pay for the train ride according to the following rules: Children younger than 6 years old ride for free. If the ticket is bought at the train station: A person over 70 years old pays $5.20, and everyone else pays $11.50. If the ticket is bought inside the train, there is an extra charge of 15% compared to train station prices. A person’s age is within the range of 0 to 120 years; other inputs are considered error conditions.
1.1- Inputs, Outputs and Error Conditions: Determine the inputs, outputs, and error conditions for the problem.
1.2- Algorithms: Write your algorithm using pseudocode.
1.3- Test cases: List a thorough set of test cases for your program in the format [inputs], where the inputs are separated by commas. [inputs][output]
2. Bank: Write a program that reads the customer balance, then calculates and displays the new balance after applying fees and/or interest based on the following rules: A negative balance incurs a $50 overdraft fee. A balance below $500 (but positive) incurs a $10 maintenance fee. A balance from $500 to $1000 (inclusive) gains 0.1% interest. A balance over $1000 will gain 2% interest.

4. Count Operations - Lucky Twos: Determines and displays the number of digits that are 2s in a whole number. Whole numbers are non-negative integers starting at zero. Let n be the number of digits of the whole number. What is the number of operations that are executed in the code in terms of n?
Paper For Above Instructions
The following sections address each part of the assignment given, focusing on train ticket pricing, bank fee calculations, contest operations count, and counting specific digits in numbers.
1. Train Ticket Pricing
The program will assess ticket prices based on a person's age and the location of the ticket purchase. The inputs for the program are: a person's age and whether the ticket is bought at the train station or on the train.
- Inputs: Age (integer), Purchase Location (string: "station" or "train")
- Outputs: Ticket Price (float)
- Error Conditions: Invalid Age (not in range 0-120), Invalid Location
Pseudocode
START
READ age, location
IF age 120 THEN
DISPLAY "Error: Invalid age"
ELSE IF location NOT IN {"station", "train"} THEN
DISPLAY "Error: Invalid location"
ELSE
IF age
price = 0
ELSE IF age > 70 AND location = "station" THEN
price = 5.20
ELSE IF location = "station" THEN
price = 11.50
ELSE IF age > 70 THEN
price = 5.20 * 1.15
ELSE
price = 11.50 * 1.15
END IF
DISPLAY price
END IF
END
Test Cases
Input: [5, "station"], Output: 0
Input: [75, "station"], Output: 5.20
Input: [30, "train"], Output: 13.225
Input: [40, "station"], Output: 11.50
Input: [150, "station"], Output: "Error: Invalid age"
Input: [70, "car"], Output: "Error: Invalid location"
2. Bank Fee Calculations
The program will calculate account balances based on customer deposits and applicable fees or interest. The inputs include the customer's balance.
- Inputs: Balance (float)
- Outputs: New Balance (float)
- Error Conditions: None defined, but values must not be non-numeric
Pseudocode
START
READ balance
IF balance
new_balance = balance - 50
ELSE IF balance
new_balance = balance - 10
ELSE IF balance
new_balance = balance + (balance * 0.001)
ELSE
new_balance = balance + (balance * 0.02)
END IF
DISPLAY new_balance
END
Test Cases
Input: [-10], Output: -60
Input: [300], Output: 290
Input: [600], Output: 600 + 0.6 = 600.6
Input: [1500], Output: 1500 + 30 = 1530
3. Count Operations - Contest
The number of operations to determine prizes for the Java programming hours based on the specific implementation is variable depending on the algorithm used. Assume a basic implementation with a direct mapping from hours to prizes.
Minimum Operations
Minimum operations occur with a direct lookup table structure, resulting in constant operations based on input; thus minimum is 1.
Maximum Operations
Maximum operations would occur in a conditional ladder if every hour range had separate if statements, e.g., 24 checks for 24 hours (1 for each hour from 1 to 24).
4. Count Operations - Lucky Twos
The program will need to iterate through each digit of the whole number. The number of operations is directly related to the number of digits n.
In terms of operations executed, if n is the number of digits, it would take O(n) operations to process the number, where n is a count of the digits in the number.
