Let's walk through the algorithm together. Initially, when the value is 50, it performs integer division by 5, giving a quotient of 10. Since 10 matches, it moves down the algorithm. Now, if we input 5 and perform the same steps, it should also be divided and checked similarly.
For example, when the next input is 50, it divides 50 by 5, getting 10, which matches. We then add the value to the total. If the input is 52, dividing 52 by 5 gives 10.4, which doesn't match, so it's rejected.
Let's see more inputs:
- For 555: Dividing by 5 gives 111, but proper division by 10 gives 55.5, so it's rejected.
- For 57: Division by 5 gives 11, but proper division gives 11.4, so it's rejected.
- For 500: Dividing by 5 gives 100, which matches, so it's added to the total, making it 550.
Finally, when the input is -1, it terminates further inputs and outputs the total, which is 550. If all calculations are correct, you score full marks.
The purpose of the algorithm is to check if a number is divisible by both 5 and 10. If it is, the number is added to the total.
Next, let's solve the logic expression problem. Given the expression Z = 1 if A = 1 AND NOT C AND B = 1 NOR C = 1:
- First, identify the logical operations: AND, NOT, NOR.
- Draw the logic gates accordingly: AND gates for A and NOT C, NOR gate for B and C.
- Complete the truth table by applying these operations step-by-step, ensuring each logical operation is correctly reflected in the table.
Lastly, for the database problem:
- Identify fields and records: Fields (5) and Records (12).
- Explain the primary key: It uniquely identifies a record.
- Assign data types: Alphanumeric for type, Boolean for private, Integer for rate dollar and number guest.
- Use SQL to filter and display records: SELECT name, number_guest, rate_dollar FROM site_one WHERE number_guest grater than or equal to 10.
Review these steps carefully, ensure proper sequence and accuracy, and you'll score full marks. Remember to subscribe, share, and let me know what more you need. Happy learning!
