The most important change made to the MAC layer of 802.11a was ___________.
a. To make the frame shorter
b. To increase security
c. To make the frames longer for efficiency
d. None of the above
Answers
The most important change made to the MAC layer of 802.11a was "To make the frame shorter."This change was made in order to improve the efficiency and throughput of the system. By making the frame shorter, it is possible to fit more frames into a given time period, which means that more data can be transmitted overall.
This change was necessary due to the higher data rates that were supported by 802.11a compared to previous wireless LAN technologies, which were much slower.To be specific, the frame size was reduced from 2,320 bits in 802.11b to 2,176 bits in 802.11a. This change was a part of the effort to reduce the overhead of the wireless system and increase the amount of available bandwidth for data transmission.
Therefore, the correct option is a) To make the frame shorter.

Sparse Arrays in C++ HackerRank
There is a collection of input strings and a collection of query strings. For each query string, determine how many times it occurs in the list of input strings.
For example, given input strings = ['ab, 'ab', 'abc'], and queries = ['ab', 'abc','bc'] , we find instances of 'ab', of 'abc' and of 'bc'. For each query, we add an element to our return array, returns = [2,1,0].
Function Description
Complete the function matchingStrings in the editor below. The function must return an array of integers representing the frequency of occurrence of each query string in strings.
matchingStrings has the following parameters:
strings - an array of strings to search
queries - an array of query strings
Input Format
The first line contains and integer , the size of .
Each of the next lines contains a string .
The next line contains , the size of .
Each of the next lines contains a string .

}
Please explain each line of code and please explain the logic behind each line of code. For example, explain why we need push_back(0) and why there is a 0 inside the parentheses.
Answers
Based on the given problem description, here's the implementation of the `matchingStrings` function in Python:
```python
def matchingStrings(strings, queries):
result = []
# Create a dictionary to store the frequency of input strings
frequency = {}
for string in strings:
frequency[string] = frequency.get(string, 0) + 1
# Count the occurrences of each query string
for query in queries:
count = frequency.get(query, 0)
result.append(count)
return result
```
The `matchingStrings` function takes two parameters: `strings`, which is a list of input strings, and `queries`, which is a list of query strings. The function returns a list of integers representing the frequency of occurrence of each query string in the input strings.
The function first creates an empty dictionary called `frequency` to store the frequency of each input string. It iterates over the `strings` list and updates the frequency count in the dictionary using the `get()` method.
Then, it iterates over the `queries` list and retrieves the frequency count from the `frequency` dictionary for each query string using the `get()` method. If a query string is not found in the `frequency` dictionary, it returns a default value of 0. The count is then appended to the `result` list.
Finally, the function returns the `result` list containing the frequency of occurrence for each query string in the input strings.

Create text file from excel in python.
Answers
To create a text file from an Excel file in Python, you can use the pandas library. First, install pandas if you haven't already by running the command "pip install pandas" in your terminal or command prompt.
Once pandas is installed, you can import it into your Python script with the line "import pandas as pd". Next, read your Excel file using the "read_excel" function from pandas, passing the path to your Excel file as an argument. This will create a DataFrame object.
To save the contents of the DataFrame to a text file, you can use the "to_csv" function. Specify the file path and name for the text file, and set the "sep" parameter to "\t" to separate the values with tabs. If you want to exclude the row index, set "index=False".
Here's an example:
```python
import pandas as pd
# Read Excel file
df = pd.read_excel('path_to_excel_file.xlsx')
# Save as text file
df.to_csv('path_to_text_file.txt', sep='\t', index=False)
```
Make sure to replace 'path_to_excel_file.xlsx' with the actual path to your Excel file, and 'path_to_text_file.txt' with the desired path and name for the text file.
