The first step in the algorithm to calculate the positive difference between two given values, x and y, is to declare the variable Diff. This is essential as it initializes the variable that will be used to store the calculated difference between x and y. The subsequent steps involve conditional statements and arithmetic operations that utilize this declared variable to compute and store the positive difference. References: N/A (as per image provided) The image shows steps of an algorithm listed in no particular order for calculating the positive difference between two values, making it relevant for understanding or teaching algorithmic logic and sequence.

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.

The modulus operator % is used to find the remainder of a division of two numbers. When you use q % 10, you are essentially dividing q by 10 and taking the remainder, which will always be the rightmost digit of q in base 10. This is because our number system is decimal (base 10), and any number modulo 10 will yield the last digit of that number. For example, 16222 % 10 will give 2, which is the rightmost digit of 16222.

In the context of the Agile approach, the phase where new procedural code is written and certain function calls are eliminated is known as the Implementation phase. This phase involves the actual coding and development of the software, where programmers write new code and refine existing code to meet the requirements of the project. It is during this phase that the software begins to take shape, and the functionality outlined during the design phase is executed.
The Agile methodology is iterative, and the implementation phase is where each iteration's goal is to produce a working increment of the product. This phase is characterized by frequent testing and revision, as the development is aligned with user feedback and changing requirements.

Let's evaluate F(3):
* F(3) = (4 * 3) - 8
* F(3) = 12 - 8
* F(3) = 4
