Suppose we want to read a JSON file in Go. By reading, we mean that we want to convert the file data into a struct in Go.Consider the JSON file shown below that we will use to read and then convert the data into the structure.{    "users": [       {          "name": "Mukul Latiyan",          "social": {             "facebook": "https://facebook.com/immukul",             "twitter": "https://twitter.com/immukul",             "linkedin": "https://linkedin.com/immukul"          }       },   ...

In this article, we will understand how to get input from the user in Java. Java provides a built-in Scanner Class that belongs to the java.util package. The Scanner class is used to get user input. In this article, we will learn how to take different types of input, like integers, floating numbers, strings, etc., from the user in Java. Algorithm Following are the steps to get input from the user - Step 1- START Step-2- Import the Scanner class Step 3- Create a Scanner object Step 4- Prompt the user to enter ... Read More

In Java, to read input from standard input(via keyboard), Java provides a built-in Scanner Class. In this article, we will understand how to read a number from standard input(via keyboard) in Java. The Scanner.nextInt() method of the Scanner class belongs to java.util package is used to read the number. The java.util.Scanner.nextInt() method scans the next token of the input as an int. The nextInt() method reads numbers in base-10 (decimal numbers) by default. To read numbers in other bases, like binary or hexadecimal, you can use nextInt(radix). Problem Statement Write a Java program to read a number from standard input. ... Read More

To compute the bit-wise AND of a 1D and a 0D array element-wise, use the numpy.bitwise_and() method in Python Numpy. Computes the bit-wise AND of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator &.The 1st and 2nd parameter are the arrays, only integer and boolean types are handled. If x1.shape != x2.shape, they must be broadcastable to a common shape. The where parameter is the condition broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array ... Read More

To return the data of a masked array as an ndarray, use the ma.getdata() method in Python Numpy. Returns the data of a (if any) as an ndarray if a is a MaskedArray, else return a as a ndarray or subclass if not.The subok parameter suggest whether to force the output to be a pure ndarray (False) or to return a subclass of ndarray if appropriate (True, default).A masked array is the combination of a standard numpy.ndarray and a mask. A mask is either nomask, indicating that no value of the associated array is invalid, or an array of booleans ... Read More

To return the mask of a masked array, use the ma.getmaskarray() method in Python Numpy. Returns the mask of arr as an ndarray if arr is a MaskedArray and the mask is not nomask, else return a full boolean array of False of the same shape as arr.A masked array is the combination of a standard numpy.ndarray and a mask. A mask is either nomask, indicating that no value of the associated array is invalid, or an array of booleans that determines for each element of the associated array whether the value is valid or not.StepsAt first, import the required ...

To compute the bit-wise AND of a 1D and a 2D array element-wise, use the numpy.bitwise_and() method in Python Numpy.Computes the bit-wise AND of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator &.The 1st and 2nd parameter are the arrays, only integer and boolean types are handled. If x1.shape != x2.shape, they must be broadcastable to a common shape.The where parameter is the condition broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array will retain ... Read More

To compute the bit-wise AND of two 1D arrays element-wise, use the numpy.bitwise_and() method in Python Numpy. Computes the bit-wise AND of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator &.The 1st and 2nd parameter are the arrays, only integer and boolean types are handled. If x1.shape != x2.shape, they must be broadcastable to a common shape.The where parameter is the condition broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array will retain its original ... Read More

To compute the bit-wise AND of two 2D arrays element-wise, use the numpy.bitwise_and() method in Python Numpy. Computes the bit-wise AND of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator &.The 1st and 2nd parameter are the arrays, only integer and boolean types are handled.

To determine whether input is an instance of masked array, use the ma.isMaskedArray() method in Python Numpy. This function returns True if x is an instance of MaskedArray and returns False otherwise. Any object is accepted as input.A masked array is the combination of a standard numpy.ndarray and a mask. A mask is either nomask, indicating that no value of the associated array is invalid, or an array of booleans that determines for each element of the associated array whether the value is valid or not.StepsAt first, import the required library −import numpy as np import numpy.ma as maCreating a ...
