$1-$ The production process in a polyester factory is carried out separately on weekdays and

weekends. Follow the instructions and write the C# console application of a program that

finds how many days the production lines will work according to the demand from the

customer.

$(50$ pts$.)$

There are three production lines in the factory, $L1,L2,L3.$ The production capacity of

L$1,L2$ and $L3$ bands is $100,200$ and $300,$ respectively.

On the weekends, the production capacity of the production lines is halved $($becomes

half$).$

The order quantity of the product will be entered from the keyboard.

The production line will be selected by user. If the user enters a wrong line number, for

example $"$L$4",$ the program must throw an error.

When the calculation of the production day is finished, the user will be informed.

Here are some tips while you are creating your chart:

Specify min $4$ variables $($such as Qty$,$ Total etc.$)$

Use modulus operation when calculating the total. $($For the $6^{th}$ and the $7^{th}$ days.$)$

Do not forget to increase the day for each step.
