Global variables are those that have been declared outside of the specified function. These are not restricted to a particular function, therefore any available function can be used to access and alter global variables. Global variables are variables that may be accessed across the whole programme and are defined outside of any individual functions or blocks. Any software function that is present can access it. A global variable is one that may be accessed from anywhere. Temporary variables used in a single function declaration are examples of local variables since they are only available inside the current scope.

Suppose a program has the following linked list: HEAD A B C D And the goal of the program is to make node "B" the new head of the linked list and move node "A" to the end of the list. The resulting linked list should be B->C->D->A Which of the options below is the correct implementation of the program? a.head=head->next; head->next->next->next->next = nullot head->next->next->next->next = head, b.head=head->next; head->next->next->next->next = head, head->next->next->next->next = nulieta c.head->next->next->next->next = nullptr.
head-head->next head->next->next >next->next = head, d.head>next->next->next->next = head head=head->next head->next->next->next->next = nullptr
Answers
The correct implementation of the program is head=head->next; head->next->next->next->next = head, head->next->next->next->next = null. The correct option is b.
To make node "B" the new head of the linked list, we set the head pointer to point to node "B" using the statement "head = head->next;". Then, to move node "A" to the end of the list, we need to make the next pointer of node "D" point to node "A" and make the next pointer of node "A" point to null.
This can be achieved with the statement "head->next->next->next->next = head, head->next->next->next->next = null;". Therefore, the correct option b correctly implements these steps, while the other options have syntax errors or do not achieve the desired result.

Give one reason why a telephone number would be stored as the text data type. [2 marks]
Answers
Answer:
Telephone numbers need to be stored as a text/string data type because they often begin with a 0 and if they were stored as an integer then the leading zero would be discounted.
The other reason is that you are never likely to want to add or multiply telephone numbers so there is no reason to store it as an integer data type.
Explanation:
A text data type can hold any letter, number, symbol or punctuation mark. It is sometimes referred to as 'alphanumeric' or 'string'.
The data can be pure text or a combination of text, numbers and symbols.
People often assume that a telephone number would be stored as an 'integer' data type. After all, they do look like numbers don't they!

a. return 3*x
b. def g(x): return 4*x
c. print(f(g(2)))
Answers
The output of the given code is "None".
Let's break down the code step by step:
1. First, we define a function called "f" with a parameter "x".
2. In option a, the "f" function returns the value of 3 multiplied by "x".
3. In option b, a new function called "g" is defined inside the "f" function. The "g" function returns the value of 4 multiplied by "x".
4. In option c, the "f" function is called with the argument "g(2)". This means that the "g" function is called with the argument 2 first. The "g" function will return the value of 4 multiplied by 2, which is 8. Then, the "f" function is called with the result of "g(2)", which is 8. However, since the "f" function does not have a return statement, it does not produce any output.
Therefore, when the code is executed, it will print "None" as the output.

Briefly, explain the specific functional elements involved in a global logistics process; global networks for shippers and carriers; INCOterms; and critical importance of cargo insurance and liability in global transactions.
Answers
The global logistics process involves various functional elements such as transportation, warehousing, inventory management, and customs compliance. It relies on global networks for shippers and carriers to facilitate the movement of goods.
INCO terms are internationally recognized trade terms that define the responsibilities and obligations of buyers and sellers in global transactions. Cargo insurance and liability are of critical importance in global transactions to protect against loss, damage, or liability during the transportation of goods.
The global logistics process encompasses several functional elements that are essential for the movement of goods across international borders. These elements include transportation, which involves selecting the appropriate mode of transport (such as air, sea, or land) and managing the transportation logistics. Warehousing plays a crucial role in global logistics by providing storage facilities for goods before they are shipped or distributed. Inventory management ensures the availability of goods at the right time and in the right quantity. Customs compliance is vital to ensure that goods comply with customs regulations and requirements in different countries.
Global networks for shippers and carriers are essential for coordinating and managing logistics operations. These networks connect various parties involved in the supply chain, including manufacturers, suppliers, freight forwarders, and transportation providers. They enable efficient communication, collaboration, and tracking of shipments throughout the logistics process.
Incoterms, short for International Commercial Terms, are internationally recognized trade terms that define the obligations, costs, and risks associated with the transportation and delivery of goods. They provide a standardized framework for buyers and sellers to clarify their responsibilities in global transactions.
Cargo insurance and liability are critical aspects of global transactions. Cargo insurance protects against loss, damage, or theft of goods during transportation. It provides financial coverage to compensate for any potential losses. Liability refers to the legal responsibility and potential financial obligations of parties involved in the transportation of goods. Ensuring appropriate cargo insurance and understanding liability issues is crucial to mitigate risks and protect the interests of all parties involved in global transactions.
In summary, the global logistics process involves functional elements such as transportation, warehousing, inventory management, and customs compliance. Global networks facilitate coordination between shippers and carriers. INCOterms define the responsibilities of buyers and sellers in global transactions, and cargo insurance and liability play a vital role in protecting against potential losses and liabilities in the transportation of goods.

Find the maximum number of paths between any two vertices of a

Answers
The maximum number of paths between any two vertices of a tree can be determined using the formula `n(n-1)/2A tree is a connected graph having no encryption cycles.
In a tree with `n` vertices, the maximum number of paths between any two vertices can be determined using the formula `n(n-1)/2`. This formula is derived as follows: For a given vertex, there are `n-1` vertices that it can be connected to directly (excluding itself).
Therefore, the maximum number of paths from this vertex is `n-1`.Similarly, for each of the `n-1` vertices that are connected to the first vertex, there are `n-2` vertices that they can be connected to (excluding themselves and the first vertex). Therefore, the maximum number of paths from each of these vertices is `n-2`.Continuing this pattern for all `n-1` vertices, we get the following sum:`(n-1) + (n-2) + (n-2) + ... + 1 = (n-1) + ((n-2) + (n-3) + ... + 1) = (n-1) + ((n-2)(n-1)/2) = n(n-1)/2`Therefore, the maximum number of paths between any two vertices of a tree with `n` vertices is `n(n-1)/2`.
