use 8086 assembly language and plz write comments

You are helping your fellow students in explaining the arithmetic sum of first n numbers. For reference purpose you are required to write 8086 assembly code to compute the sum of first n natural numbers using recursive function and display the explanation as well, as shown in the sample execution for your fellow students.

Recursive function is given as sum(n) = n + sum(n-1)

You are also required to display the following output for the purpose of explanation. (Marks 15)

Sample Execution:

Enter the value of n= 5

Sum of first 5 natural number is = 15

Explanation: 1 + 2 + 3 + 4 + 5 =15
