Bankers algorithm is mostly used in banking systems to determine whether or not to grant a loan to a certain applicant.

For this reason, we use the banker's algorithm to identify the safe state and the safe sequence, such as P2, P4, P5, P1, and P3. In order to grant the Request (1, 0, 2), we must first verify that Request = Available, which means that (1, 0, 2) = (3, 3, 2) since the condition is true. Thus, the request is received instantly by process P1.

The banker's algorithm is a resource allocation and deadlock avoidance algorithm that simulates resource allocation for predetermined maximum possible amounts of all resources, performs a "s-state" check to look for potential activities, and then determines whether allocation should be permitted to continue.

(a) One possible recurrence to solve this problem is:

Let f(i, j) be the maximum sum of a nearly contiguous subarray ending at index j and starting at index i or before.

Then the recurrence can be written as:

f(i, j) = max(f(i, j-1), f(i, j-2) + A[j])

This recurrence calculates the maximum sum of a nearly contiguous subarray ending at index j and starting at index i or before by considering two possibilities:

The subarray does not include the element at index j. In this case, the maximum sum is the same as the maximum sum ending at index j-1.

The subarray includes the element at index j, but skips the element at index j-1. In this case, the maximum sum is the sum of the elements ending at index j-2 plus the element at index j.

(b) Another possible recurrence to solve this problem is:

Let g(i, j) be the maximum sum of a contiguous subarray ending at index j and starting at index i or before.

Then the recurrence can be written as:

g(i, j) = max(g(i, j-1) + A[j], A[j])

This recurrence calculates the maximum sum of a contiguous subarray ending at index j and starting at index i or before by considering two possibilities:

The maximum sum of the subarray includes the element at index j. In this case, the maximum sum is the sum of the maximum sum ending at index j-1 plus the element at index j.

The maximum sum of the subarray does not include the element at index j. In this case, the maximum sum is simply the element at index j.

(c) To calculate the final overall answer, we can input the values 0 and n-1 into both recurrences, where n is the length of the array A. This will give us the maximum sum of a nearly contiguous subarray that starts at the beginning of the array and ends at the end of the array.

(d) To implement these recurrences using memoization, we can use a two-dimensional array to store the calculated values of f and g. The array can be initialized with values of 0 for all indices, and then we can fill in the values starting from the bottom right corner and working our way towards the top left corner.

(e) The running time of this algorithm would be O(n^2), because we need to calculate the values of f and g for every possible pair of indices i and j. This requires O(n^2) time in the worst case.
