PROBLEM $1.$

Modify the MATLAB program of Tutorial $\backslash$#$3$ so that the code becomes a simple digital calculator.

$\backslash (\backslash$checkmark $\backslash )$ At the beginning of your code, ask the user to input an arithmetic operator symbol $(+,-,*,\backslash ()\backslash ).$ Note that the operator symbol has to be a "string" entry. After that, ask the user to input the first number, and store it as: number$1.$ Then, ask the user to input the second number, and store it as: number$2.$ Finally, write the four $(4)$ case statements to perform each arithmetic operation. For each operation, the program should calculate and return the respective result in the Command Window.

The Command Window Output should look like:

$```$

Enter an operator: $+$

Enter the $1$st number: $5$

Enter the $2$nd number: $4$

result $=$

$9$

$```$
