Consider the following C++ code fragment: int a = 3; int b = 2; double r = a/b; Suppose we want r to have the value 1.5, rather than 1. Which cast operator can be used in the third line to achieve this effect? a. static cast b. dynamic cast c. reinterpret cast d. none of the above
Write a Java program called E2b that will read from StdIn an integer, n, and will set the size of a 2D array to have n rows and n columns. The values in this n x n 2D array must be read from StdIn and the array must be filled in row-major order. For example, if the following input stream was read: 4 1 2 3 4 4 3 2 1 9 8 7 6 5 7 6 4 The 2D array created would be: 1 2 3 4 4 3 2 1 9 8 7 6 5 7 6 4 Include in the program above, code that would print the values in the 2D array beginning with the value in the last row, last column and ending with the value in the 0th row, 0th column, traversing the columns from bottom to top, printing n values in each row of the output. The values in the array do not change. You are simply printing them in a unique order.

The output should be saved in two class idx.Reminder: Remember to index np.where() at zero # TODO two_class_idx = np.where(y == 2 )[0] print(f"two_class_idx output: \n {two_class_idx}") try: print(f"two_class_idx shape: {two_class_idx.shape}") except Exception: pass ([ (isinstance(two_class_idx, np.ndarray),f'two_class_idx is not an NumPy array! two_class_idx is currently a {type(two_class_idx)}'), (np.all(two_class_idx == np.array([3,9,11,12,16])),'two_class_idx does not contain the correct location values') ])
Write a Java program that implements parallel programming using the Fork/Join framework. And must make use of the subclasses in the Fork/Join Framework. Step1- The program should initially generate 15 million random numbers. Step2-The generated numbers should be read into an array of doubles. Step 2- Then use a method that uses this array to calculate the sum of these doubles. Step 3-It must then display the sum and it must also output the number of processors available. Lastly, Have a clear screenshoot of code in the IDE and a screenshot of the code running.
Write a Java code # Resistor ColorResistors have color coded bands, where each color maps to a number. The first 2 bands of a resistor have a simple encoding scheme: each color maps to a single number.These colors are encoded as follows:- Black: 0- Brown: 1- Red: 2- Orange: 3- Yellow: 4- Green: 5- Blue: 6- Violet: 7- Grey: 8- White: 9Mnemonics map the colors to the numbers, that, when stored as an array, happen to map to their index in thearray: Better Be Right Or Your Great Big Values Go Wrong.More information on the color encoding of resistors can be found in the [Electronic color code Wikipedia article]# Running the testsYou can run all the tests for an exercise by entering $ gradle test in your terminal.## SourceMaud de Vries, Erik Schierboom [https://github.com/exercism/problem-specifications/issues/1458] Consider the structure that the code must have; it is given in the picture
