Create a program that asks the user to enter a series of strings and uses a condition$-$controlled loop with a sentinel for the inputs.$$ The program creates a new string by joining the entered strings together.$$ Then, the program displays the created string.

For example, if the user enters the strings Scratch, is$,$ a$,$ cat, the program outputs Scratchisacat.

Notes:

Use an appropriate sentinel to exit the loop $($i$.$e$.$ the sentinel should be something that cannot be mistaken for an entered string$).$

In the same loop for the inputs, create the join of the entered strings.$$

You will not receive full credit if your program asks the user to enter the number of strings to be entered.$$ That is$,$ do not include an input that asks the user how many strings they want to enter.$$ The point of this program is to practice using a sentinel to stop the loop.

For full credit, the inputs and outputs must include appropriate sentences.
