Computational Systems

The computation systems can be defined as the systems that are capable of solving a problem that includes calculations either mathematical or logical, and are able to produce the result as an output. For example, a simple calculator that is given a set of numbers and operators as input and produces the result as an output can be defined as a computational system. The above example is a simple illustration only, the computational systems range from simple devices to complex devices such as the systems that control the SpaceX companies, Starlink satellites which are being quite recently seen in the skies at many places globally.

write a function

is_valid_station(name) that returns if name is a valid station name

use python.

Boston Subway
The Boston Subway e has four different colored trains, some of which have multiple
routes. We have simplified the routes so that each train has a single route with the
following stations (in order from north to south) and that each colored line intersects
with another colored line at exactly one station.
• Red Line: Alewife, Davis, Porter, Harvard, Central, Kendall/MIT, Charles/MGH,
Downtown Crossing, South Station, Broadway, Andrew, JFK/UMass
• Orange Line: Oak Grove, Malden Center, Wellington, Assembly, Sullivan Square,
Community College, North Station, Haymarket, State, Downtown Crossing,
Chinatown, Tufts Medical Center, Back Bay, Mass Avenue, Ruggles, Roxbury
Crossing, Jackson Square, Stony Brook, Green Street, Forest Hills
• Blue Line: Wonderland, Revere Beach, Beachmont, Suffolk Downs, Orient Heights,
Wood Island, Airport, Maverick, Aquarium, State
• Green Line: Haymarket, Government Center, Park Street, Boylston, Arlington,
Copley, Haynes Convention Center, Kenmore, Blandford Street, Boston University
East, Boston University Central, Boston University West, Saint Paul Street,
Pleasant Street, Babcock Street, Packards Corner, Harvard Avenue, Griggs Street,
Allston Street, Warren Street, Washington Street, Sutherland Road, Chiswick Road,
Chestnut Hill Avenue, South Street, Boston College
Station names must match exactly (unforgiving about upper/lowercase and
abbreviations) with the exception of names that have a "/" in them. These stations can
be referred to be either one. For example, both "Kendall" and "MIT" refer to the same
station.
Note: The simplification of our train lines is such that each line intersects with other
lines in exactly one station. But not all lines intersect every other line.

You are the chief commander of US Army; you have been deployed in an ongoing war training of defusing the mine. Mines are placed on the ground which can be considered as a gird of size N*M. Each block (i, j) has a mine in it if and only if the summation of the block coordinates is divisible by 2. Your task is to move from the first row to the last row. The mines will not blow if the given rules are followed: • If you are on even row you can move to any cell that is in the neighborhood • If you are on odd row, you can only go the odd row that has mine on that and same with the unmined row. You have to develop a python program to calculate the number of ways to reach row number N starting from row number 1. Test Cases: 4 8 Output: 10
As a teaching administrator of the department, your responsibility is to schedule the classes for a particular classroom. Suppose there are n classes, each class i is represented by its start time and finishing time [Si, fi], and we say that two classes i and j are non-conflicting if they do not overlap in time (i.e., sizfj or szfi). You want to schedule as many classes for the classroom as possible, but the scheduled classes should be non-conflicting. Develop an algorithm so that you can select the maximum number of classes for the classroom. (We are expecting either pseudocode or language description of your algorithm)
Primary U.S. interstate highways are numbered 1-99. • Odd numbers (like the 5 or 95) go north/south, and even numbers (like the 10 or 90) go east/west. • Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, 1-405 services 1-5, and 1-290 services 1-90. Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also, indicate if the (primary) highway runs north/south or east/west. Use the information above to write several functions to help you determine this information. Call these functions in your main program to produce the requested output. Instructions The functions Write a function get_direction () that expects a highway number. • Returns a string "north/south" if the highway number is odd (like the 5 or 95); • Returns "east/west" if the highway number is even (like the 10 or 90). If the function is called with the following input 290 the…

Page There is a famous railway station in PopPush City. Country there is incredibly hilly. The station was built in last century. Unfortunately, funds wwere extremely limited that time. It was possible to establish only a surface track. Moreover, it turned out that the station could be only a dead-end one (see picture) and due to lack of available space it could have only one track. 5, 4, 3, 2, 1 1, 2, 3, 4, 5 Station The local tradition is that every train arriving from the direction A continues in the direction B with coaches reorganized in some way. • Assume that the train arriving from the direction A has NS 1000 coaches numbered in increasing order 1, 2, .
