Write a program for the LMC environment that takes a variable number of user inputs until the

user enters $0.$ The program then prints out the sum of the user inputs.

For example, if the user enters $5,1,11,12,2$ and $0,$ then the program returns $31.$ If the user

enters $2,1$ and $0,$ the program returns $3.$

Write a short $($one paragraph, $150$ words max.$)$ explanation how the sum was arrived at$.$ In the

document, provide a screenshot showing your code and the corresponding output.
