array.py
● Create a program called array.py that has a function that takes four integer arguments. Those arguments should be put into an Numpy array. The function will have two print statements. The first will print the type of the array you create (which should be ). The second will print the sum of the four items in your array.
● Your output could look like this (it could differ in parts):
X482: Make Perfect Array
The mere presence of oversized arrays makes Priscilla Perfect sick to her stomach. Such wasted space is an imperfection she cannot bear. As her oldest and dearest friend this worries you greatly. If you
were a doctor you might try to find a cure to her sickness, but you are a programmer. A program must be written to alleviate her pain!
For any array given that has empty slots create a new array that is perfect. Unused slots will have a value of 0. All unused slots are guaranteed to be at the end of the array. There will never be unused
slots in the middle.
java.util.Arrays has been enabled.
Examples:
makePerfect({1, 1, 4, 5, 6, 0, e, e, 0}) -> {1, 1, 4, 5, 6}
makePerfect({1, 3, 4, 2, 6, 0, e, e, 0}) -> {1, 3, 4, 2, 6}
JAVA PROGRAM
Chapter 7. PC #16. 2D Array Operations
Write a program that creates a two-dimensional array initialized with test data. Use any primitive data type that you wish. The program should have the following methods:
• getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array.
• getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array.
• getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row.
• getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the…

- (Electrical eng.) Write a program that declares three one-dimensional arrays named volts, current, and resistance. Each array should be declared in main() and be capable of holding 10 double-precision numbers. The numbers to store in current are 10.62, 14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, and 3.98. The numbers to store in resistance are 4, 8.5, 6, 7.35, 9, 15.3, 3, 5.4, 2.9, and 4.8. Your program should pass these three arrays to a function named calc_volts(), which should calculate elements in the volts array as the product of the corresponding elements in the current and resistance arrays (for example ,volts[1]=current[1]resistance[1]). After calc_volts() has passed values to the volts array, the values in the array should be displayed from inside main().arrow_forwardarray.py Create a program called array.py that has a function that takes four integer arguments.

- Programming: Multi-Array Assignment Instructions Overview Using a two-dimensional array, you will create the game battleship using a text file that contains the board. The user will enter coordinates to try and find ships and sink them. Instructions Imagine you are using a two-dimensional array as the basis for creating the game battleship. In the game of battleship, a `~' character entry in the array represents ocean (i.e., not a ship), a `#' character represents a place in the ocean where part of a ship is present, and a `H' character represents a place in the ocean where part of a ship is present and has been hit by a torpedo. Thus, a ship with all `H' characters means the ship has been sunk. Declare a two-dimensional array that is 25 x 25 that represents the entire ocean and an If statement that prints "HIT" if a torpedo hits a ship given the coordinates X and Y. Create a text file of 25 line. Each line has 25 characters. ~ represents water and # represents part of…arrow_forwardFill-in-the-Blank Array names can be used as __________ and vice versa.arrow_forwardFill-in-the-Blank By using the same _________ for multiple arrays, you can build relationships between the data stored in the arrays.
