This tutorial will discuss how to write swift program to calculate the sum of elements in a given array. An array is an ordered collection which is used to store same type of data. For example, if any array is of integer type then it will only store integers, you are strictly not allowed to store elements of other data types like string, float, etc. Syntax Following is the syntax for an array − var array1 = [val1, val2, val3, …] Or var array2 = [Type]() Suppose we have an array of integer type: [20, 30, 40, 50]. Now ... Read More

This tutorial will discuss how to write swift program to get the magnitude of the number. An array is an ordered collection which is used to store same type of data. For example, if any array is of integer type then it will only store integers, you are strictly not allowed to store elements of other data types like string, float, etc. To remove all the elements from the specified array Swift provide an in-built library function named removeAll(). The removeAll() function will delete all the items from the specified array. Or it can delete elements that match the given ... Read More

This tutorial will discuss how to write swift program to remove an element from the set. Set is a primary collection type in Swift. It is an unordered collection which stores unique values of same data type. You are not allowed to store different type of values in the same set. A set can be mutable or immutable. To remove an element from the set Swift provide an in-built library function named remove(). The remove() function delete the given element from the specified set. If the given element is not the part of the specified set, then it will return ... Read More

This tutorial will discuss how to write swift program to add a new element in the set. Set is a primary collection type in Swift. It is an unordered collection which stores unique values of same data type. You are not allowed to store different type of values in the same set. A set can be mutable or immutable. To add a new element in the set Swift provide the following functions − insert() update() Below is a demonstration of the same − Input Suppose our given input is − MySet = [23, 45, 1, 46, 2] Insert ...

This tutorial will discuss how to write swift program to convert a string to uppercase. A string is a sequence of characters for example, “RedCar”. Or we can say, string are used to represent textual data. Swift support a String data type which is used to create a String type variable, or we can say to represent strings. To convert the given string into uppercase Swift provide a in-built function named uppercased(). The uppercased() function is used to convert all the characters(either in lowercase or in uppercase or in both) of the given string into uppercase. This function does not ... Read More

This tutorial will discuss how to write swift program to get a random element from the Set. Set is a primary collection type in Swift. It is an unordered collection which stores unique values of same data type. You are not allowed to store different type of values in the same set. A set can be mutable or immutable. Syntax Following is the syntax for Set − var name : Set = [element1, element2, element3] To get a random element from the Set Swift provide an in-built function named randomElement(). This function return a random element from the given ... Read More

This tutorial will discuss how to write swift program to get the size of set. Set is a primary collection type in Swift. It is an unordered collection which stores unique values of same data type. You are not allowed to store different type of values in the same set. A set can be mutable or immutable. To get the size of a Set Swift provide an in-built property named count. It will return the total number of elements present in the specified count. Below is a demonstration of the same − Input Suppose our given input is − MySet ... Read More

In this article, we will show you what is a sparse matrix and how to create a sparse matrix in python. What is a sparse matrix? A sparse matrix is one in which most of the elements are 0. That is, the matrix only contains data in a few positions. And most of the memory consumed by a sparse matrix is made up of zeroes. For example − M = [ [1, 0, 0, 0], [0, 0, 3, 0], [0, 0, 0, 0], [0, 0, 0, 2] ] ... Read More

Vectors in C++ are dynamic arrays that can contain any type of data, it can be user-defined or primitive. Dynamic is in the sense that the size of a vector can increase or decrease according to the operations. Vectors have support for various functions, for which data manipulation is very easy. Lists on the other hand are containers same as vectors, but list implementation is based on doubly linked lists compared to the array implementation of vectors. Lists offer the same constant time operations anywhere in it, that is the main feature of using lists. We take a look at ... Read More
