In this article, we will learn how to write a swift program to search an element in an Array. Here we use the following methods to search elements from the given array: To search Using == operator Using contains() method Using the in function Method 1: Using == operator To search for an element from the given array we iterate through each element of the given array and check if the element is equal to the specified element using the == operator. If true, then the specified element is present in the array. Otherwise not. Algorithm ... Read More

In this article, we will learn how to write a swift program to remove duplicate elements from an array. As we know that an array can store multiple elements of the same type. It is not necessary that all the elements are unique they can be duplicated. For example, arr = [3, 5, 6, 3, 7, 8, 3, 7, 7] here 3 and 7 are duplicate elements. So here we use the following methods to remove duplicate elements − Using contains() method Using Set() initializer Method 1: Using contains() method To remove duplicate elements from the array we ...

In this article, we will learn how to write a swift program to print the absolute value of complex numbers. Complex numbers are those numbers which express in the form of x+yi, where x and y are real numbers and ‘i’ is an imaginary number known as iota. For example 4+2i, 6-4i, etc. Now the absolute value of the complex number is the positive square root of the sum of the squares of the real and the imaginary parts. $\mathrm{|\:Absolute\:Value\:|\:=\:\sqrt{(real)^{2}\:+\:(img)^{2}}}$ For example − Complex number = 4 + 2i $\mathrm{|\:Absolute\:Value\:|\:=\:\sqrt{(4)^{2}\:+\:(2)^{2}}}$ $\mathrm{=\:\sqrt{16 + 4}}$ $\mathrm{=\:\sqrt{20}}$ = 4.4721359549995 Algorithm Step 1 − ...

In this article, we will learn how to write a swift program to print a matrix in Z form. Here we traverse through the first row then the secondary diagonal and then the last row of the matrix to print the z form. For example, 4x4 Matrix − $\mathrm{\begin{bmatrix}4 & 1 & 4 & 1 ewline1 & 3 & 1 & 3ewline2 & 1 & 1 & 2ewline1 & 6 & 6 & 1\end{bmatrix}}$ So the Z form numbers are − $\mathrm{\begin{bmatrix}4 & 1 & 4 & 1 ewline & & 1 & ewline & 1 & & ...

In this article, we will learn how to write a swift program to print an identity matrix. Identity matrix is a square matrix in which the main diagonal elements contain only one and the rest of the elements are 0. For example − $\mathrm{Matrix\:=\:\begin{bmatrix}1 & 0 & 0 & 0 & 0 ewline0 & 1 & 0 & 0 & 0 ewline0 & 0 & 1 & 0 & 0ewline0 & 0 & 0 & 1 & 0ewline0 & 0 & 0 & 0 & 1\end{bmatrix}}$ Algorithm Step 1 − Create a function. Step 2 − In this function, use ... Read More

In this article, we will learn how to write a swift program to multiply two matrices by passing the matrix to a function. A matrix is a mathematical structure in which the elements are present in rows and columns format. For example, the first element is present at the a00 location, the second at a01, and so on. So to multiply two matrices, we multiply the mth row of the first matrix by an nth column of the second matrix and add the products. This will create an element at the mth row and nth columns of the resultant matrix. ... Read More

In this article, we will learn how to write a swift program to multiply two matrices using multi-dimensional arrays. A matrix is a mathematical structure in which the elements are present in rows and columns format. For example, the first element is present at the a00 location, the second at a01, and so on. Therefore, to multiply two matrices, we multiply the mth row of the first matrix by an nth column of the second matrix and add the products. This will create an element at the mth row and nth columns of the resultant matrix. For example − ... Read More

In this article, we will learn how to write a swift program to initialize and print complex numbers. Complex numbers are those numbers which express in the form of x+yi, where x and y are real numbers and ‘i’ is an imaginary number known as iota. Alternatively, we can say that a complex number is a combination of both real and imaginary numbers. For example 1+2i, 1-3i, etc. In Swift, we use a struct to create complex numbers. Algorithm Step 1 − Create a structure using the struct keyword. Step 2 − In this structure, create two properties ... Read More

In this article, we will learn how to write a swift program to get the real part from the complex number. Complex numbers are those numbers which express in the form of x+yi, where x and y are real numbers and ‘i’ is an imaginary number known as iota. For example, 2+2i, 1-3i, etc. where 2 and 1 are the real part and 2i and -3i is the imaginary part. Here we use the following methods to get the real part − Using the function Without using the function Method 1: Using the function To get the real ... Read More

In this article, we will learn how to write a swift program to get the numerator from a rational number. A rational number is a number which represents in the form of n/m where m is not equal to zero. Here n is known as the numerator and m is known as the denominator. For example, 7/9, 13/23, etc. Here, 7 and 13 are numerators whereas 9 and 23 are denominators. Algorithm Step 1 − Create a structure to create a rational number. Step 2 − In this structure, create two properties of integer type to store the numerator and ... Read More
