質問 # 30
What happens if one element of a NumPy array is changed to a string?

• A. All elements in the array are coerced to strings.
• B. The array becomes a list of the original integers.
• C. All elements in the array are coerced to integers.
• D. The operation is not allowed and raises an error.

正解：D

解説：
A central rule in NumPy is that an ndarray has a single, fixed data type called itsdtype. That dtype is chosen when the array is created (for example, int64, float64, etc.), and it normally does not change just because you assign a new value into one element. When you attempt an assignment, NumPy tries tocastthe assigned value into the array's existing dtype. If the cast is possible, the assignment succeeds; if the cast is impossible, NumPy raises an error.
So, if you have a numeric array such as arr = np.array([1, 2, 3]), its dtype is an integer type. Trying arr[0] =
"hello" cannot be converted into an integer, so NumPy raises a ValueError (a casting/conversion error). This is exactly the behavior textbooks highlight when contrasting NumPy arrays with Python lists: lists can hold mixed types freely, but NumPy arrays trade that flexibility for speed and memory efficiency via uniform typing.
Option A is a common misconception. While NumPy may "upcast" values to a more general dtype at array creation time when mixed types are provided (e.g., numbers and strings in the same constructor), a pre-existing numeric array will not automatically convert itself into a string array during a single- element assignment. Options C and D do not reflect NumPy's assignment rules.

質問 # 31
What is the component of the operating system that manages core system resources but allows no user access?

• A. User interface layer
• B. The kernel
• C. The File Explorer
• D. Device driver manager

正解：B

解説：
Thekernelis the central component of an operating system responsible for managing core system resources. It controls CPU scheduling, memory management, process creation and termination, device I/O coordination, and system calls-the controlled interface through which user programs request services. In operating systems textbooks, the kernel is described as running in a privileged mode (often called kernel mode or supervisor mode), which restricts direct user access for security and stability. User programs typically run in user mode and cannot directly manipulate hardware or critical OS structures; instead, they must request operations via system calls, which the kernel validates and executes.
This separation prevents accidental or malicious actions from crashing the entire system or compromising other processes. For example, a user application cannot directly write to arbitrary memory addresses or reprogram devices; the kernel mediates access and enforces protection boundaries. This model is foundational to modern OS design and underpins features like virtual memory, access control, and multitasking.
File Explorer and the user interface layer are user-facing components that provide interaction and file browsing; they are not the privileged core resource manager. "Device driver manager" is not typically the name of a single OS component; while drivers and driver subsystems exist, they operate under kernel control and are part of the kernel or closely integrated with it.
Therefore, the OS component that manages core resources while disallowing direct user access is the kernel.

質問 # 32
Which method allows a user to convert a string value to all capital letters in Python?

• A. upperCase()
• B. toUpperCase()
• C. upper()
• D. makeUpper()

正解：C

解説：
In Python, strings are objects of type str, and the language provides many built-in string methods for common transformations. The standard method used to convert all alphabetic characters in a string to uppercase is upper(). For example, "Hello, World".upper() produces "HELLO, WORLD". This method is part of Python's core string API and is documented as returning anewstring because strings are immutable in Python; the original string is not modified.
Options A and D resemble methods from other programming languages. For instance, toUpperCase() is commonly seen in Java and JavaScript, not Python. Option B, makeUpper(), is not a standard method in Python's str type. Python's naming conventions for built-in methods are typically short and lowercase, which is consistent with upper(), lower(), strip(), and replace().
It is also important to note what upper() does and does not do. It affects letters according to Unicode case-mapping rules, so it works beyond ASCII and supports many languages. Non-alphabetic characters such as digits, punctuation, and whitespace remain unchanged. Because the method returns a new string, it supports functional-style programming and safe reuse of the original data. In many textbook examples, upper() is paired with input normalization tasks, such as case-insensitive comparisons and cleaning user-entered text.

What is the time complexity of a binary search algorithm?

• A. O(n
