Before privatization, the form of electronic media that was the result of a collaboration between the U.S. government and higher education was:

the ARPANET.

ARPANET (Advanced Research Projects Agency Network) was the first operational packet switching network and the predecessor to the global Internet.

It was created in the late 1960s as a collaboration between the U.S. Department of Defense's Advanced Research Projects Agency (ARPA) and several universities.

The goal of ARPANET was to develop new computer communication technologies and to explore the potential for wide-area networking. The success of ARPANET paved the way for the widespread commercialization of the Internet.

The first message sent on the ARPANET network was sent by computer science researcher Charley Kline from the University of California, Los Angeles to computer science researcher Bill Duvall at the Stanford Research Institute on October 29, 1969.

If traffic on the internet were akin to a stream of water, the internets bandwidth is equivalent to  the width of the stream.

Bandwidth refers to the maximum amount of data that can be transmitted over a network connection in a given amount of time. The bandwidth of the internet, therefore, is a measure of the maximum capacity of the network to transfer data. In the analogy of the stream of water, the bandwidth can be thought of as the width of the stream, where a wider stream can carry more water (or data) at once, and a narrower stream can carry less.

Having a high bandwidth is important for applications that require large amounts of data to be transferred quickly, such as video streaming or online gaming. A low bandwidth, on the other hand, can result in slow or unreliable network connections, leading to long wait times and buffering for users.

Overall, the bandwidth of the internet is a crucial factor in determining the speed and performance of the network, and efforts are constantly being made to increase the bandwidth and improve the overall experience for users.

A null value in a database refers to the absence of a value or the undefined value in a column.

SQL A particular marker called a NULL value is used in SQL to denote the absence of a data value in the database. In other terms, it stands for a value that does not exist or a value that is unknown. Understanding the concept of NULL values in SQL is crucial since they might have an impact on the outcomes of your queries and cause unexpected behavior.

An empty string or a value of zero are not the same as a NULL value. A NULL value denotes an unknown or nonexistent value, but an empty string is a legal value that represents the empty string. A NULL value indicates that the value is unknown, whereas a value of zero is a legitimate number.

To identify columns that cannot accept null values in SQL, you can use the following query:

SELECT column_name

FROM information_schema.columns

WHERE table_name = 'your_table_name'

AND is_nullable = 'NO';

This query will return the names of all columns in the table your_table_name that do not allow null values.

Answer:

One way to solve this problem is to use a two-pointer approach.

Explanation:

Start with the first two elements of the subarray and move the second pointer forward until the sum of the elements is greater than or equal to k. Then, move the first pointer forward by one and repeat the process. Keep track of the number of subarrays that meet the condition and return that count as the result. This solution has a time complexity of O(n) since each element is only processed once.

This problem can be solved using sliding window technique. We will keep a window of size m and move it from the leftmost position to the rightmost position, checking the sum of every pair of integers inside the window. If the sum is greater than or equal to k, we increment the count of subarrays with the desired property.

The sliding window technique is a common algorithm used in computer science, especially in the field of data structures and algorithms. It is a technique for efficiently processing arrays, lists or any other data structures by dividing the data into smaller overlapping windows and processing each window in a specific manner.

This problem can be solved using sliding window technique. We will keep a window of size m and move it from the leftmost position to the rightmost position, checking the sum of every pair of integers inside the window. If the sum is greater than or equal to k, we increment the count of subarrays with the desired property.

Here's the implementation in Python:

def subarrays_with_sum_greater_than_k(a, m, k):

count = 0

for i in range(len(a) - m + 1):

window = a[i:i+m]

for j in range(m):

for k in range(j+1, m):

if window[j] + window[k] >= k:

count += 1
