Swift program to Print Pyramid Star Pattern
This tutorial will discuss how to write swift program to print pyramid star pattern. Star pattern is a sequence of “*” which is used to develop different patterns or shapes like pyramid, rectangle, cross, etc. These star patterns are generally used to understand or practice the program flow controls, also they are good for logical thinking. To create a pyramid star pattern, we can use any of the following methods − Using nested for loop Using init() Function Using stride Function Below is a demonstration of the same − Input Suppose our given input is − ...
Read MoreSwift Program to Find Maximum Key-Value Pair in the Dictionary
This tutorial will discuss how to write swift program to find maximum key-value pair in the dictionary. A dictionary is used to store data in the form of key-value pair in the collation without any defined-order. Here the type of the keys are same as well as the type of the values are also same. Each key is behave like an identifier for the associate value inside the dictionary and each value has a unique key. Swift dictionary is just like the real dictionary. It loop up values according to their identifier. Syntax Following is the syntax for creating dictionary ...

Read MoreSwift Program to Check Armstrong Number
This tutorial will discuss how to write swift program to check Armstrong number. The sum of nth power of individual digit of a number is equal to the number itself, then such type of number is known as Armstrong number. Suppose we have a number 407 so here n = 3 153 = 13 + 53 + 33 153 = 1 + 125 + 27 153 = 153 Hence 153 is Armstrong number Suppose we have another number 8973, so here n = 4 8973 = 84 + 94 + 74 + 34 8973 = 4096 + 6561 + 2401 ...
Read MoreSwift Program to Display Armstrong Number Between Two Intervals
This tutorial will discuss how to write swift program to display Armstrong number between two intervals. The sum of nth power of individual digit of a number is equal to the number itself, then such type of number is known as Armstrong number. Suppose we have a number 407 so here n = 3 407 = 43 + 03 + 73 407 = 64 + 0 +343 407 =407 Hence 407 is Armstrong number Suppose we have another number 2346, so here n = 4 2346 = 24 + 34 + 44 + 64 2346 = 16 + 81 + ...
Read MoreSwift Program to Find Geometric Mean of the Numbers
This tutorial will discuss how to write swift program to find the geometric mean of the numbers. Geometric mean also known as GM. Geometric mean is defined as the xth root of the product of x numbers. Suppose we have x elements(that are, a1, a2, a3, ....ax) in the given array, then the geometric mean is − GM = (a1 * a2 * a3 * a4 * ....*ax)1/x Below is a demonstration of the same − Input Suppose our given input is − MyVal = [34, 67, 2, 45, 8, 12] Output The desired output would be − Geometric ...
Read MoreSwift Program to Find Mean of an Unsorted Array
This tutorial will discuss how to write swift program to find mean of an unsorted 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]() Mean represent the average of the given numbers. It is calculated by dividing the sum of ...
