a. First-order logic statement to express the contract:

Let R represent "it rains on Monday," J represent "John gives Mary a $100 check on Tuesday," and M represent "Mary mows the lawn on Wednesday." Then, the contract can be expressed as:

(R → J) ∧ (J → M)

The first part (R → J) states that if it rains on Monday, then John must give Mary a $100 check on Tuesday. The second part (J → M) states that if John gives Mary a $100 check on Tuesday, then Mary must mow the lawn on Wednesday. The two parts are connected with a conjunction (∧) to express both conditions of the contract.

b. Logical statement to express what truly happened:

¬R ∧ J ∧ M

The statement describes that it did not rain on Monday (¬R), John gave Mary a $100 check on Tuesday (J), and Mary mowed the lawn on Wednesday (M). The three events are connected with a conjunction (∧) to express that all of them happened.

The implementation of once-only tokens and timestamping sessions can help prevent replay attacks.

Replay attacks occur when an attacker intercepts and maliciously reuses previously captured data or session information. By implementing once-only tokens, each token can be used only once. Once a token is used, it becomes invalid, preventing an attacker from replaying the same token to gain unauthorized access.

Timestamping sessions involves including a timestamp in the session data or authentication process. The timestamp provides a time reference, ensuring that the session data or authentication request is only valid within a specific time window. If an attacker attempts to replay a session or authentication request outside the valid time window, it will be rejected as invalid.

Together, once-only tokens and timestamping sessions provide a layered approach to prevent replay attacks. The once-only tokens ensure that captured tokens cannot be reused, and the timestamping ensures that session data or authentication requests are time-limited and cannot be replayed after a certain timeframe.

By implementing these security measures, the system can mitigate the risks associated with replay attacks. It helps maintain the integrity and confidentiality of data and ensures that only valid and current session data or authentication requests are accepted.

In conclusion, the implementation of once-only tokens and timestamping sessions provides protection against replay attacks. It achieves this by preventing the reuse of intercepted tokens and by time-limiting the validity of session data or authentication requests. These security measures enhance the overall security posture of the system and help safeguard against unauthorized access and data compromise.

To define a SCHEME function unzip that takes a list of pairs ((a1, b1), ..., (an, bn)) and returns a pair consisting of the two lists (a1, ..., an) and (b1, ..., bn).

Define a SCHEME function called unzip:

1. Start by defining the function with the `define` keyword:
```scheme
(define (unzip pairs)
```

2. Add a base case to check if the input list `pairs` is empty:
```scheme
 (if (null? pairs)
```

3. If the input list is empty, return two empty lists:
```scheme
     '(() ())
```

4. Otherwise, recursive call the `unzip` function on the `cdr` (tail) of the input list and use `cons` to construct the resulting lists with the elements from the `car` (head) of the input list:
```scheme
     (let ((rest (unzip (cdr pairs))))
       (cons (cons (caar pairs) (car rest))
             (cons (cdar pairs) (cadr rest))))))
```

5. Close the parentheses to complete the function definition.

Here's the complete function:

```scheme
(define (unzip pairs)
 (if (null? pairs)
     '(() ())
     (let ((rest (unzip (cdr pairs))))
       (cons (cons (caar pairs) (car rest))
             (cons (cdar pairs) (cadr rest))))))
```

This unzip function works by recursively processing the input list of pairs, extracting the first elements (a1, ..., an) and the second elements (b1, ..., bn) and combining them into two separate lists.

The C++ program demonstrates a simple and efficient way to find the most occurring element in an array of characters. It can be useful in many applications where we need to find the most common character in a text or a string.

Here is the C++ program to find the most occurring element in an array of characters:

c++
#include
using namespace std;

char mostOccurringChar(char arr[], int size) {
   int count[256] = {0};  // initialize count array with all zeros
   int max = -1;
   char result;

   for (int i = 0; i < size; i++) {
       count[arr[i]]++;
       if (max < count[arr[i]]) {
           max = count[arr[i]];
           result = arr[i];
       }
   }
   return result;
}

int main() {
   char arr[] = {'a', 'b', 'c', 'a', 'd', 'a', 'b', 'c', 'c', 'c'};
   int size = sizeof(arr) / sizeof(arr[0]);

   char mostOccurring = mostOccurringChar(arr, size);

   cout << "The most occurring element is: " << mostOccurring << endl;

   return 0;
}


The above C++ program finds the most occurring element in an array of characters. It uses an array called 'count' to keep track of the count of each character in the array. It initializes the count array with all zeros. Then, it loops through the array and increments the count of each character. It also keeps track of the maximum count and the character associated with it. Finally, it returns the character with the maximum count.

To write a program that takes an unlimited number of 10-item sets and displays them after each one is entered, we can use a loop that continues until the user decides to stop entering sets. Within the loop, we can prompt the user to enter each set and store it in a list.

Once the list contains 10 items, we can print it out and clear the list to start accepting the next set. Here is an example implementation of the program in Python:

```
sets = []
while True:
   set_input = input("Enter a 10-item set (separated by spaces): ")
   set_items = set_input.split()
   if len(set_items) != 10:
       print("Set must contain exactly 10 items. Try again.")
       continue
   sets.append(set_items)
   print("Current sets:")
   for s in sets:
       print(s)
   if input("Enter another set? (y/n)") == "n":
       break

print("Final sets:")
for s in sets:
   print(s)

print("You have earned $10 for using this program!")
```

This program uses a `while` loop to continue accepting sets until the user chooses to stop. It prompts the user to enter a 10-item set and checks that it contains exactly 10 items before adding it to the `sets` list. After each set is added, it prints out all the sets entered so far. Once the user is done entering sets, it prints out all the sets again and rewards the user with $10 for using the program.

Overall, this program provides a simple way for users to enter and view multiple sets of items, making it useful for a variety of applications.

Based on the given information, a recommended storage policy would be a class-based storage policy for fast items and a random storage policy for slow items.

Since the fast items are responsible for 80% of the movement in and out of the warehouse, it would be beneficial to have them stored together in a designated area, such as a specific aisle or section of the warehouse. This would allow for faster and more efficient picking and replenishment processes, as well as potentially reducing the risk of errors or misplacements.

On the other hand, since the slow items only contribute to 20% of the movement, a random storage policy would be more suitable for them. This means that they can be stored in any available location throughout the warehouse, without being grouped together based on any specific criteria. This allows for more flexible use of the warehouse space and can potentially reduce the amount of time spent searching for specific items.

Alternatively, a dedicated storage policy for fast and slow items could also be considered. This would involve having separate areas or even separate warehouses for the two types of items. However, this approach may not be as cost-effective or practical for all warehouses.
