To find the largest integer k such that both k and -k exists in an array of integers, we can use a simple algorithm that iterates through the array and keeps track of the largest positive and negative numbers encountered so far. The largest value that satisfies the condition will be the maximum of the absolute values of these two numbers.

Here is a sample function in Python that implements this algorithm:

def largest_k(a):
   max_pos = 0
   max_neg = 0
   for i in a:
       if i > 0 and i > max_pos:
           max_pos = i
       elif i < 0 and abs(i) > abs(max_neg):
           max_neg = i
   return max(abs(max_pos), abs(max_neg))

This function takes an array of integers as input and initializes two variables max_pos and max_neg to zero. It then iterates through the array, checking each integer and updating max_pos and max_neg if necessary. If an integer is positive and greater than max_pos, it replaces max_pos. If an integer is negative and has a greater absolute value than max_neg, it replaces max_neg. Finally, the function returns the maximum of the absolute values of max_pos and max_neg, which is the largest integer k such that both k and -k exist in the array.

Euler's formula for a planar graph states that for a planar graph with n vertices, m edges, and r regions (including the outer region), we have:

n - m + r = 2

Now, let's apply this formula to the planar graph H with no cycles of length 3, 4, or 5. Since H is planar, we can draw it in the plane without any edges crossing. This divides the plane into regions, including the outer region.

Each region must have at least three sides, since otherwise we would have a cycle of length 2 or 1. Moreover, each side of a region must belong to a different edge of the graph, since otherwise we would have a cycle of length 3, 4, or 5. Therefore, the number of sides of the regions is at least 3r.

On the other hand, each edge of the graph belongs to exactly two sides of the regions, since an edge separates two regions. Therefore, the number of sides of the regions is exactly 2m.

Using these observations, we can adjust Euler's formula for the graph H as follows:

n - m + r = 2

n - m + (2m/3) ≥ 2 (since each region has at least 3 sides)

3n - 3m + 2m ≥ 6 (multiplying both sides by 3)

3n - m ≥ 6

m ≤ 3n - 6

Therefore, we have derived the inequality for the upper bound on the number of edges in a planar graph with n vertices and no cycles of length 3, 4, or 5, which is m ≤ 3n - 6.

Assuming that there's a table named pledges with columns donor_id, status, and payment_plan, the procedure checks if there's at least one row that matches the input donor ID, has an active status, and is on a monthly payment plan.

Here's an example of how to test the procedure with an anonymous block:

DECLARE result BIT;

EXEC result = ddpay_sp donor_id = 12345;

SELECT result AS has_active_monthly_pledge;

This declares a variable result of type BIT (which can hold either 0 or 1), executes the ddpay_sp procedure with a donor ID of 12345, and selects the result as a column named has_active_monthly_pledge.

The problem with the given recursive function is that it will cause an infinite loop, as there is no base case to terminate the recursion.

The function will continuously call itself with a decreasing value of 'n', and eventually result in a stack overflow error or crash the program.

A base case is required in a recursive function to specify a condition where the function stops calling itself and returns a value, thus preventing an infinite loop. Without a base case, the function will continue to call itself indefinitely, leading to the aforementioned issues.

Therefore, to make this recursive function work correctly, a base case must be defined. For instance, we can add an if-statement that checks if n is less than or equal to 0, and if so, simply return without any further recursive calls. This way, the function will stop calling itself when n reaches 0, and the recursion will be properly terminated.

User-level threads are managed entirely by the user-level library, without any involvement of the kernel. On the other hand, kernel-level threads are managed by the kernel itself.

In Linux, the threads created by the clone() system call can be considered kernel-level threads, as they are created and managed by the kernel. However, Linux also supports a thread library called NPTL (Native POSIX Thread Library), which provides user-level threads.

The surface of a hard disk is organized into tracks and pie-shaped groups of sectors. A sector is the smallest unit of storage on a hard disk and contains a fixed number of bytes, typically 512 or 4096. Each track is a concentric circle on the disk and contains a number of sectors.

The number of sectors per track varies depending on the distance from the center of the disk to the track. Tracks closer to the center of the disk have fewer sectors than tracks farther away from the center. This is because the circumference of a track closer to the center of the disk is shorter than the circumference of a track farther away from the center.

The pie-shaped groups of sectors are called sectors zones. Each sector zone contains a group of tracks with the same number of sectors per track. The number of sectors per track in a sector zone is optimized for the disk's read/write head and varies depending on the disk's design. The read/write head moves across the surface of the disk to access data stored in different sector zones. The organization of the disk's surface into tracks and sector zones allows the read/write head to quickly locate the data it needs to access.
