In microscopy, what are the three main factors to obtain a good image?.
Answers
In microscopy, the three main factors to obtain a good image are resolution, contrast, and magnification.Resolution refers to the ability of the microscope to distinguish between two separate points in a sample.
It is determined by the wavelength of light or electrons used in the microscope. The shorter the wavelength, the better the resolution. Contrast refers to the difference between the object and the background in an image. This can be achieved by staining or labeling the sample to make it stand out from its surroundings. Magnification refers to the size of the image compared to the actual size of the object. This can be adjusted by changing the lenses in the microscope.The combination of these three factors is critical to obtaining a clear and accurate image in microscopy.
Without sufficient resolution, it is impossible to distinguish small details in the sample. Without good contrast, the object may blend in with the background and become difficult to see. And without proper magnification, the sample may be too small to see clearly. Therefore, a balance between resolution, contrast, and magnification is necessary to achieve a good image in microscopy.

Answer:

Explanation:
OrderID + ProductID is an example of a composite key in a database table. The correct option is 4.
What is composite key?A composite key is a key in a database table that consists of two or more columns that uniquely identify each row.
In a database table, a composite key is the combination of OrderID and ProductID in a table that tracks sales transactions.
Because a single order can contain multiple products and multiple orders can contain the same product, neither column can uniquely identify a row by itself.
However, by combining the two columns, each row can be uniquely identified, ensuring that the data is accurate and complete.
Similarly, a combination of CustomerID and ProductID might be used in a sales system to track the products purchased by each customer.
Thus, the correct option is 4.

calling a function with name _ is done with free_func()
Answers
In regards to calling a function with name _ is done with free_func(), It is generally not a good idea to name a function with an underscore as the first character. In many programming languages, including Python, names that begin with an underscore are considered private or "special" and are typically used to indicate internal implementation details of a class or module.
These names are not intended to be accessed directly by users of the class or module and are subject to change without notice.
What is the calling function about?It is possible to call a function with an underscore in its name, but it is generally better to use a more descriptive and meaningful name for your functions. This can help to make your code more readable and maintainable, and can also help to avoid potential conflicts with reserved words or other special names in the language.
So, For example, instead of using a name like _func, you might consider using a name like process_data or calculate_result, depending on the purpose of the function.

Explanation:
std::vector (available via #include ) is a generic template class and a C++ construct. Vector is a dynamic array that grows and shrinks dynamically as needed:
To overcome integral size limitation (INT_MAX, DOUBLE_MAX, etc) we want to devise a software solution to store a number that can be VERY LARGE. To do that we have a positive number (N >= 1) whose digits are stored in a vector. For instance 123 is stored as [1, 2, 3] in the vector. 54321 is stored as [5, 4, 3, 2, 1] in the vector.
Write the following function that simulates --N by taking in its vector representation as the function parameter. The function returns the result of --N in its vector form:
vector minusMinusN(vector v)
EXAMPLES
input: [1,2]
output: [1,1]
input: [1]
output: [0]
input: [1,0]
output: [9]
input: [1,0,0]
output: [9,9]
input: [9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9]
output: [9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,9,8]
input: [9,2,3,9]
output: [9,2,3,8]
STARTER CODE
#include
#include
using namespace std;
/**
* PURPOSE:

* RETURN VALUES:

vector minusMinusN(vector digits) {
// YOUR CODE HERE
}
int main() {
// your target function will be tested like so, with random input
vector v {1,0};
vector retVal = minusMinusN(v); // retVal = [9]
// etc.
return 0;
}
CONSTRAINTS / ASSUMPTIONS
Your inputs come straight from main(...) NOT cin, getline(...), etc., inside the above given function you have to write
N >= 1; the input vector v is NOT empty.
N can be very large, exceeding all integral limits in C++.
Answers
Here's the implementation of the `minusMinusN` function that simulates --N by decrementing the given vector representation of a number:
```cpp
#include <iostream>
#include <vector>
using namespace std;
vector<int> minusMinusN(vector<int> digits) {
int n = digits.size();
int i = n - 1;
while (i >= 0 && digits[i] == 0) {
digits[i] = 9; // Subtracting 1 from a digit of 0 results in 9
i--;
}
if (i >= 0) {
digits[i] -= 1;
}
if (digits[0] == 0 && n > 1) {
digits.erase(digits.begin()); // Remove leading zeros if any
}
return digits;
}
int main() {
vector<int> v {1,0};
vector<int> retVal = minusMinusN(v); // retVal = [9]
for (int digit : retVal) {
cout << digit << " ";
}
cout << endl;
return 0;
}
```
The function `minusMinusN` takes in a vector `digits` representing a positive number. It starts by finding the last non-zero digit in the vector and subtracts 1 from it. If the resulting digit is still non-zero, the process stops. Otherwise, it continues subtracting 1 from the previous digits until a non-zero digit is encountered or the beginning of the vector is reached. Leading zeros are then removed if any. Finally, the updated vector is returned.
In the example provided, the input vector is [1, 0]. The function decrements the last digit, resulting in [1, 9]. As there are leading zeros, the final output is [9].
The `minusMinusN` function effectively simulates the decrement operation on a large number represented by a vector. It handles cases where there are leading zeros and ensures that the resulting vector representation is correct. This solution allows us to store and manipulate very large numbers that exceed the integral limits in C++.
