 The type of language that requires variables to be declared ahead of time and prohibits their types from changing while the program runs is known as a statically typed language. In statically typed languages, the type of a variable is determined at compile-time and cannot be changed during runtime. This means that the compiler must know the exact data types of all variables used in the program, and these types must remain consistent throughout the execution of the program. Statically typed languages require developers to declare the type of each variable before using it, which can help catch type errors during the compilation process, potentially preventing runtime errors and bugs.

• Initialize two variables: x and Count to zero.
• Iterate through each number in the NumList.
• For each number in the list:
• After processing all numbers in the list, calculate the average:

The NumList contains the following integers: [1, 3, 5, 6, 7, 8].

Calculating the average: (1 + 3 + 5 + 6 + 7 + 8) / 6 = 30 / 6 = 5.0.

However, none of the provided options match this result. It seems there might be an error in either the options or the calculation.

A while loop is used to repeatedly execute a block of code as long as a specified condition is true. In the context of the given options:

• Option A could use a simple if-else statement to compare two numbers and print the larger one.
• Option B is a classic example of a use case for a while loop. The loop can run until the correct password is entered or the maximum number of attempts is reached.
• Option C could be accomplished with a single if statement to check if the number is a multiple of 10.
• Option D can also be done with an if-else statement to check the properties of the number.

Therefore, the task that is best suited for a while loop is Option B, where the user is asked to enter a password repeatedly until a correct password is entered or a certain number of incorrect attempts have been made. This requires the program to loop through the password prompt and check the conditions after each input, which is what while loops are designed for.

The code snippet not (g != S) contains two types of operators:

• Equality Operator (!=): The expression g != S checks whether the value of g is not equal to the value of S. The != operator is used for comparison and returns True if the values are different, otherwise False.
• Logical Operator (not): The not operator is a logical negation operator. It inverts the truth value of a Boolean expression. In this case, not (g != S) evaluates to True if g is equal to S, and False otherwise.

Therefore, the combination of these two operators results in the overall expression not (g != S).
