Final answer:
The student's task is to write a C program to manipulate a sequence of natural numbers based on calculations such as mean and finding extremes, which is a computer science-related question, likely college level due to its complexity.
Step-by-step explanation:
The student's question involves a series of steps that align with programming in C. It requires inputting a number n, performing calculations on a sequence of n natural numbers, and manipulating the sequence according to a set of instructions, all of which are common tasks in computer science coursework, particularly in a college-level context.
This task involves calculating the mean of the sequence, locating the smallest and maximum values, replacing values in the sequence, and finally, modifying and outputting the rearranged sequence. While the question suggests the application of mathematical concepts, the essence of the task is deeply rooted in computer programming, making Computers and Technology the most appropriate subject.
