We are given an array of any size containing integer elements and the task is to calculate the count of elements that are present in the first array but not in the second array..Arrays a kind of data structure that can store a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.For exampleInput− int arr_1[] = {1, 2, 3, 4}       Int arr_2[] = {1, 5, 6, 7, ...

In this article, we have an unsorted array of integers having repetitive elements. Our task is to count the distinct elements in the given array in C++. Example Here is an example of counting the unique number in the given array: Input: array = {4, 2, 32, 26, 57, 52, 40, 2, 57, 40, 33} Output: Distinct elements in the array: 8 Here is a list of approaches for counting distinct elements in the given array: Using Nested for Loop Using Sorting ...

We are given with a binary tree and the task is to calculate the count of non-leaf nodes available in a binary tree.Binary Tree is a special data structure used for data storage purposes. A binary tree has a special condition that each node can have a maximum of two children. A binary tree has the benefits of both an ordered array and a linked list as search is as quick as in a sorted array and insertion or deletion operation are as fast as in linked list. Non-leaf nodes are also known as parent nodes as they have more ... Read More

We are given a circular linked list with the nodes and the task is to calculate the count of nodes present in a circular linked list.Circular Linked List is a variation of Linked list in which the first element points to the last element and the last element points to the first element. Both Singly Linked List and Doubly Linked List can be made into a circular linked list.In the below program, we are implementing a singly linked list as a circular linked list to calculate the count of nodes in that.For ExampleInput − nodes-: 20, 1, 2, 3, 4, ...

We are given with an array of n integers and the task is to calculate the count all the triplets whose sum is equal to perfect cubeWhat is the perfect cubeA perfect cube is a number which is a cube of any number, like 125 is a cube of 5 so we can say that 125 is a perfect cube. Some of the perfect cube integers are 1, 8, 27, 64, 125….So, according to the problem in the array we have to find and count those triplets (set of 3 values) whose sum is equal to a perfect cube number. ...

We are given a string with, let’s say, str and the task is to compute the count of characters in a string str having the same neighbors and that will include both left and right side of a character in a string. Also, in this scenario the first and last character in a string will always be considered as they have only one adjacent character.For ExampleInput − string str = “poiot” Output − count is 3Explanation − In the given string characters p, t and i are having the same neighbors so the count will be increased to 3.Input − ...

We are given a range having start and end and the task is to calculate the count of hexadecimal numbers or alphabets present in the given range.What are Hexadecimal Alphabets?In computer terms, hexadecimal numbers are those numbers that are having base 16 which means the binary digit can be represented in 16-bit. It consists of integer numbers starting from 0-15. Where 10 is represented as A, 11 as B, 12 as C, 13 as D, 14 as E and 15 as F.So, in the below program our task is to find whether the range consists of hexadecimal alphabets or not.For ... Read More

We are given a string of any length containing both uppercase and lowercase letters and the task is to compute the count of those characters whose ASCII values are prime.The ASCII values of uppercase letters[A-Z] start with 65 till 90 and lowercase letters[a-z] starts with 97 till 122.For ExampleInput string str = ‘Aebg’ Output count is: 2Explanation − The ASCII value for A is 65 which is a non-prime number so it willn’t be counted, e is 101 which is a prime number so it will be counted, b is 66 which is a nonprime number so it willn’t be ...
