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

Swift has various functions like flatmap(), compactmap(), reduce() to flatten an 1D array. An array is used to store elements of same data type in an order whereas a set is used to store distinct elements of same data type without any definite order. Method 1: Using flatmap() Function To flatten 2D array into 1D array we can use flatmap() function. The flatmap() function return an array by concatenating the sub arrays into a single array. Syntax func flatMap{_res} Here, res is a closure which accepts the element of the specified array as its argument and return a flattened ... 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 will learn how to write a swift program to convert an array into a string and join elements with a specified character. An array is used to store elements of same data type in an order. Here we use the following methods to join elements of the array with a specified character − Using joined(separator:) function Without using inbuilt function Method 1: Using joined(separator:) Function So to convert an array into a string and join elements with a specified character we use joined(separator:) method. This method is used to concatenate the elements of the ... Read More

To check if the given string is numeric or not we use Double() initializer in Swift Programming. A string is an ordered collection of characters for example “Sky”. A string can be numeric and non-numeric. A numeric string is a string which only contains numbers for example “12345”. So the valid numeric strings are: “3423”, “222333”, “34.342”, etc., whereas non-valid numeric strings are “23hfd23”, “423131sdd”, etc. So it converts the given string into double and return true if the given string is numeric otherwise return false. Algorithm Step 1 − Create a function Step 2 − Return ... Read More

A matrix is an arrangement of numbers in rows and columns. A matrix has two diagonals i.e. Right diagonal and Left diagonal. So here we calculate the sum of the right diagonal of the square matrix using Swift Programming. For example, we have the following matrix − Matrix = 3 4 5 5 3 2 1 8 1 The right diagonal elements are 5, 3, 1. So the sum of right diagonal is 9(5+3+1). Algorithm Step 1 − ... Read More

A matrix is an arrangement of numbers in rows and columns. Matrix can be of various type like square matrix, horizontal matrix, vertical matrix etc. So here we calculate the sum of the left diagonal of the square matrix using Swift Programming. A square matrix is a matrix in which the number of rows and columns are same. For example 2x2, 5x5, etc. For example, we have the following matrix − Matrix = 3 4 5 1 5 3 2 2 1 ... Read More

In Go programming language, a new module is initiated using init command after which we can import other modules in our code. There is no concept of class in Go, only structs are used. In this article, we will use one example to include a module inside the class. In this example, we will create a Circle struct whose area will be printed on the console. For this example, we will import math and fmt packages outside the struct but they can be used anywhere. The print statement is executed using Printf function from the fmt package. Algorithm Import ... Read More

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
