We can create a block in golang using curly braces and then create a variable inside the block to have the scope only inside the block and not outside it. In this article, we will use three examples to create a block using curly braces. In the first example few statements will be printed inside and outside the block, in the second example comparison value will be printed inside the block and in the third example function will be used to demonstrate the use of block. Algorithm Import the required packages in the program Create a main function In ... Read More
Golang has json package that is used for converting the hask collection into strin. A hashmap belongs to hash collection which stores the data as key:value pairs, whereas a string is a sequence of characters and it is immutable. In this article, we will use two examples to convert the hash collection into string. In the first example, the Json package will be used to convert the map to encoded byte array whereas in the second example sort package will be use along the loops. Syntax json.Marshal() This function belongs to the JSON package and it converts the value ... Read More
We are going to calculate the current time using the Now function from time package in Go programming language for demonstrating the time arithmetic. The time arithmetic is calculated using mathematical functions. In both examples, we will use mathematical calculations to find the past, future and the duration using Sub function. The output is printed using Println function from the fmt package. Syntax func Now() Time The Now() function is defined in time package. This function generates the current local time. To use this function, we have to first import the time package in our program. func sub() ... Read More
As per the problem statement, we have an array with some random integer values and we need to find out the numbers which are greater than its immediate left element. Note - Take an integer array. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Given Array= [1, 2, -3, -4, 0, 5]. The numbers which are greater than its left element = 2, 0, 5 Instance-2 Given Array= [-1, 0, 4, 6, 8, -5]. The numbers which are greater than its left element = ... Read More
A parallelogram refers to the quadrilateral which has two pairs of parallel sides where opposite sides are equal in length, and the opposite angles are equal in measure. In this article we are going to find all possible coordinates of a Parallelogram. Basically, we will find all the possible coordinates from the given three coordinates to make a parallelogram of a non-zero area. Here the three given coordinates are not fixed points and can change. Therefore, if three coordinates are given, we may claim that there are only three coordinates from which we can build a parallelogram. As per ... Read More
In this article we are going to change all lower-case text to upper-case text in a file in java. Suppose the text file contains the following data − “Merry and Jack are studying.” Then after updating the text file with specific value the result will be − “MERRY AND JACK ARE STUDYING.” This modification is done with the help of toUpperCase() Method. It belongs to the String class in java. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose the original content of the ... Read More
In this article, we are going to understand how to create a simple function in Haskell using user-defined function. Here, the user-defined recursive functions are defined that will contain base case and recursive case. Then, these functions are being called recursively by passing the argument to it. In all the examples, we are going to define certain functions to perform certain tasks. All these functions include, base and recursive cases. The function defined includes factorial, fibonacci, sumList, etc. Algorithm Step 1 − The user defined recursive function is defined with base and recursive case. Step 2 − ... Read More
In Haskell, we can return multiple values from the function by using user-defined function along with tuple, custom data type and Maybe data type. In the first example, we are going to use (myFunction = ("Hello, World!", 42)) and in the second example, we are going to use (data MyData = MyData { stringValue :: String, intValue :: Int }). And in third example, we are going to use, (myFunction :: Maybe (String, Int)). Method 1: Using Tuple In this method, a function can return multiple values by using a tuple. A tuple is a data structure that holds multiple ... Read More
In this article, we are going to learn how to return a string from a function using user-defined function along with record syntax and let binding. In the first example, we are going to use (myFunction = "Hello, World!") function and in the second example, we are going to use (myFunction = stringValue myData). And in third example, we are going to use let binding, (myFunction = let str = "Using let binding!" in str). Method 1: Returning a string from the user-defined function In this method, the user-defined functions are defined that will contain the function definition and return ... Read More
This article will help us learn how to pass a string to the function in Haskell with identity function and lambda expression. In the first example, we are going to use (myFunction inputString = inputString) function and in the second example, we are going to use (myFunction = id). And in third example, we are going to use lambda expression, (myFunction = \inputString -> inputString). Method 1: Passing a string to the user-defined function In this method, the user-defined functions are defined that will contain the function definition with some returning value and is being called by passing a string ...
