Count number of elements between two given elements in array in C++
We are given an array containing integer elements and two numbers start and end and the task is to calculate the count of elements present between start and end in an 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. If the start element is occurring multiple times then we will consider the first occurrence of the start element and ...
Read MoreCount elements that are divisible by at-least one element in another array in C++
We are given two arrays, let's say arr_1[] and arr_2[] both containing integer values and the task is to calculate the count of elements that are divisible by at least one element in another array. It means there we need to count those elements having at least one factor in the second array which is arr_2.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 ...
Read MoreCount number of distinct pairs whose sum exists in the given array in C++
We are given an array of, let's say, arr[] of integer values of any respective size and the task is to calculate the count of the number of distinct pairs available in a given array whose sum also exists in the same 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.Points to rememberA pair will be counted once with the ...
Read MoreCount distinct pairs from two arrays having same sum of digits in C++
We are given with two arrays let’s say, arr_1[] and arr_2[] having integer values and the task is to calculate the count of distinct pairs having the same sum of digits. It means, one value should be selected from an arr_1[] and second value from arr_2[] to form a pair and both the values should have the same sum digits.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 ...
Read MoreCount array elements that divide the sum of all other elements in C++
We are given an array let’s say, arr[] of integer values and the task is to calculate the count of array elements that divides the sum of all other elements.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[] = {9, 6, 3} Output − count is 3Explanation − As the sum of elements 9+6 = 15 ...
Read MoreCount divisors of array multiplication in C++
We are given an array let’s say, arr[] of integer elements of any given size and the task is to calculate the count of the factors of a number calculated by multiplying all the array elements.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[] = {2, 3} Output − count is 4Explanation − the multiplication of ...
Read MoreCount maximum elements of an array whose absolute difference does not exceed K in C++
We are given an array let’s say, arr[] of integer elements of any given size and a positive integer k and the task is to calculate the count of those element pairs whose absolute difference doesn’t exceed the given integer k.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[] = {2, 3, 6, 12, 14}, k= ...
Read MoreCount BST nodes that lie in a given range in C++
We are given a binary search tree made up of nodes and also a range and the task is to calculate the count of nodes that lies in the given range and display the result.A Binary Search Tree (BST) is a tree in which all the nodes follow the below-mentioned properties −The left subtree of a node has a key less than or equal to its parent node's key.The right subtree of a node has a key greater than to its parent node's key.Thus, BST divides all its sub-trees into two segments; the left subtree and the right subtree and ...
Read MoreCount number of digits after decimal on dividing a number in C++
We are given two integer numbers let’s say num1 and num2 and the task is to divide the num1 with num2 and calculate the count of digits after decimal on dividing these given numbers.For ExampleInput − num1 = 2, num2 = 5 Output − count is 1Explanation − when we divide 2 with 5 i.e. ? = 0.4, so digits after decimal is 1 therefore count is 1.Input − num1 = 2, num2 = 0 Output − Floating point exception (core dumped)Explanation − when we divide any number with 0 it will return an error and terminate the program abnormally.Input ...
Read MoreCount changes in Led Lights to display digits one by one in C++
We are given a positive number let’s say num and the task is to calculate the count of changes in the Led lights displayed one by one. We will assume that initially all LEDs are off and they will be started based upon the string value.For solving this question we need to understand what a seven segment display is and its working.What are Seven Segment DisplaysSeven segment displays are the output display device that provide a way to display information in the form of image or text or decimal numbers which is an alternative to the more complex dot matrix ...
