Prоgrаmming Quiz 100 pоints Yоu mаy not use аny online resources (other than canvas, an online textbook, and/or notes YOU wrote which are online), but may use any written or other notes that are present on your computer. You may not use any AI tools. You may structure your program however you would like (i.e., how many classes to use). What I can about is that the program works as listed below. Remember that you get partial credit so if something doesn’t work and you are stuck, please move on so you get as many points as possible. Instructions: You are creating an Airport and planes!!! You have an airport that has a runway that can hold 5 planes. A Plane has a tail number that consists of a 3-letter code. Planes land on the right side of the runway and take off from the left side. Each round, you can choose to “land” a plane, “takeoff” a plane, or you can just “pass” for the round. Each round, all the planes move one slot to the left (if they are able) - this takes place before the user operation is done but after the user enters in their input. So, the round order goes as follows: (1) ask for input (2) move the planes (3) attempt to perform the requested operation from (1). See the output for examples. Planes cannot be on top of another plane. This also means that planes cannot land if the runway is full or more to the left if there is a plane in the way. The planes cannot move off the screen either (unless they takeoff). Whenever a plane “lands” on the runway, you have to ask the user for the plane’s tail number. Each slot on the runway either has “---” or the tail number for a plane. That is, as a hint, you can use the --- to indicate (in your code) if a plane is currently there or not. Like, using equals. Each round you enter in one of the following controls. Controls: ‘L’ for land, ‘T’ for takeoff (which only succeeds if a plane is at end of runway), and ‘P’ for pass (planes move forward but no planes leave or come). *This program loops forever and does not end. You may assume the user input will be correct to my specification. Constraints (repeated from the above instructions). Planes can only land if the right slot is empty on that turn. If the user attempted to land a plane when the runway is full, be sure to note to the user that it could not be done and continue. Planes cannot move left if there is a backup of planes – don’t move a plane of the screen during the “move” operation. You don’t need to note this to the user, just don’t do move the planes. Planes only takeoff from the leftmost slot. If there is no plane to takeoff during a takeoff operation, please be sure to note it to the user. Because the planes more to the left BEFORE the operation, this means that a plane could sort of appear to take off from the second to last spot (so you put in the operation ‘T’, the plane moves from slot 2 to slot 1, and then it takes off) Sample run though: Please enter an operation: L/T/P>> PMoving...[---][---][---][---][---]Performing operation...Passing...[---][---][---][---][---]Please enter an operation: L/T/P>> LPlease enter tail number: >> 099Moving...[---][---][---][---][---]Performing operation...Attempting to land!Landing successful![---][---][---][---][099]Please enter an operation: L/T/P>> TMoving...[---][---][---][099][---]Performing operation...Attempting to takeoff!Not planes ready for takeoff![---][---][---][099][---]Please enter an operation: L/T/P>> LPlease enter tail number: >> 001Moving...[---][---][099][---][---]Performing operation...Attempting to land!Landing successful![---][---][099][---][001]Please enter an operation: L/T/P>> LPlease enter tail number: >> 002Moving...[---][099][---][001][---]Performing operation...Attempting to land!Landing successful![---][099][---][001][002]Please enter an operation: L/T/P>> LPlease enter tail number: >> 003Moving...[099][---][001][002][---]Performing operation...Attempting to land!Landing successful![099][---][001][002][003]Please enter an operation: L/T/P>> TMoving...[099][001][002][003][---]Performing operation...Attempting to takeoff!Plane in the air![---][001][002][003][---]Please enter an operation: L/T/P>> LPlease enter tail number: >> 004Moving...[001][002][003][---][---]Performing operation...Attempting to land!Landing successful![001][002][003][---][004]Please enter an operation: L/T/P>> LPlease enter tail number: >> 005Moving...[001][002][003][004][---]Performing operation...Attempting to land!Landing successful![001][002][003][004][005]Please enter an operation: L/T/P>> PMoving...[001][002][003][004][005]Performing operation...Passing...[001][002][003][004][005]Please enter an operation: L/T/P>> PMoving...[001][002][003][004][005]Performing operation...Passing...[001][002][003][004][005]Please enter an operation: L/T/P>> LPlease enter tail number: >> 123Moving...[001][002][003][004][005]Performing operation...Attempting to land!Runway to full to land.[001][002][003][004][005]Please enter an operation: L/T/P>> TMoving...[001][002][003][004][005]Performing operation...Attempting to takeoff!Plane in the air![---][002][003][004][005]Please enter an operation: L/T/P>> TMoving...[002][003][004][005][---]Performing operation...Attempting to takeoff!Plane in the air![---][003][004][005][---]Please enter an operation: L/T/P>> TMoving...[003][004][005][---][---]Performing operation...Attempting to takeoff!Plane in the air![---][004][005][---][---]Please enter an operation: L/T/P>> TMoving...[004][005][---][---][---]Performing operation...Attempting to takeoff!Plane in the air![---][005][---][---][---]Please enter an operation: L/T/P>> TMoving...[005][---][---][---][---]Performing operation...Attempting to takeoff!Plane in the air![---][---][---][---][---]Please enter an operation: L/T/P>> LPlease enter tail number: >> 909Moving...[---][---][---][---][---]Performing operation...Attempting to land!Landing successful![---][---][---][---][909]Please enter an operation: L/T/P>> TMoving...[---][---][---][909][---]Performing operation...Attempting to takeoff!Not planes ready for takeoff![---][---][---][909][---]Please enter an operation: L/T/P>> TMoving...[---][---][909][---][---]Performing operation...Attempting to takeoff!Not planes ready for takeoff![---][---][909][---][---]Please enter an operation: L/T/P>> TMoving...[---][909][---][---][---]Performing operation...Attempting to takeoff!Not planes ready for takeoff![---][909][---][---][---]Please enter an operation: L/T/P>> TMoving...[909][---][---][---][---]Performing operation...Attempting to takeoff!Plane in the air![---][---][---][---][---]
