3-digit Osiris number C Program?
An Osiris number is a special 3-digit number that equals the sum of all permutations of its 2-digit sub-samples. For example, 132 is an Osiris number because 12 + 21 + 13 + 31 + 23 + 32 = 132. Syntax bool isOsirisNumber(int n); Algorithm The approach is straightforward. For a 3-digit number, each digit appears exactly twice in the permutations − once in the tens position and once in the ones position. Therefore, we can check if the number equals 22 times the sum of its digits. Begin ...
Read MorePaged Media in CSS
Paged media differ from continuous media in that the content of the document is split into one or more discrete pages. Paged media includes paper, transparencies, pages that are displayed on computer screens, etc. The CSS2 defines a page box, a box of finite dimensions in which content is rendered. The page box is a rectangular region that contains two areas − The page area − The page area includes the boxes laid out on that page. The edges of the page area act as the initial containing block for a layout that ...
Read MoreAdd all greater values to every node in a given BST?
In this problem, we need to modify each node in a Binary Search Tree (BST) by adding the sum of all greater node values to the current node's value. This transforms the BST while maintaining its structure but changing the node values. Syntax void addGreaterValues(struct Node* root, int* sum); Problem Statement Given a Binary Search Tree, we need to add to each node the sum of all node values that are greater than the current node value. Input BST 10 5 ...
Read MoreRole of size property in CSS to set the size and orientation of a page box
The CSS size property specifies the size and orientation of a page box when printing. This property is primarily used within @page rules to control how content appears on printed pages. Syntax @page { size: value; } Possible Values ValueDescription autoThe page box will be set to the size and orientation of the target sheet landscapeOverrides the target's orientation. The longer sides are horizontal portraitOverrides the target's orientation. The shorter sides are horizontal lengthCreates an absolute page box with specified dimensions. One value sets both width and height ...
Read MoreAdd 1 to a number represented as a linked list?
The linked list representation of a number stores each digit in a separate node, where the first node contains the most significant digit and the last node contains the least significant digit. For example, the number 202345 is represented as (2→0→2→3→4→5). To add 1 to this linked list represented number, we need to handle carry propagation from the least significant digit. If the last digit is less than 9, we simply increment it. Otherwise, we propagate the carry to the next digits. Syntax struct Node* addOne(struct Node* head); Algorithm The algorithm follows these ...
Read MoreFade In Left Big Animation Effect with CSS
The CSS Fade In Left Big animation effect creates a dramatic entrance animation where an element slides in from the far left while simultaneously fading in from transparent to opaque. This effect uses translateX(-2000px) to start the element off-screen. Syntax @keyframes fadeInLeftBig { 0% { opacity: 0; transform: translateX(-2000px); } 100% { opacity: 1; ...
Read MoreFade In Down Animation Effect with CSS
The CSS Fade In Down animation effect creates a smooth transition where an element gradually appears while moving downward from its starting position. This animation combines opacity changes with vertical translation to create an elegant entrance effect. Syntax @keyframes fadeInDown { 0% { opacity: 0; transform: translateY(-distance); } 100% { opacity: 1; transform: ...
Read MoreA Number Link Game?
Number Link is a logic puzzle where players must connect matching numbers on a grid using continuous paths. The paths cannot cross or branch, and each number must be at the endpoint of exactly one path. This implementation generates a random Number Link puzzle and its solution using a union-find data structure. Syntax struct _node { struct _node *parent; int rank; int path_number; int endpoint; }; Algorithm Overview The algorithm works by generating random paths first, then creating ...
Read MoreFade In Left Animation Effect with CSS
The CSS Fade In Left animation effect creates a smooth transition where an element slides in from the left while gradually becoming visible. This animation combines opacity changes with horizontal movement to create an elegant entrance effect. Syntax @keyframes fadeInLeft { 0% { opacity: 0; transform: translateX(-20px); } 100% { opacity: 1; transform: ...
Read MoreC program to calculate the value of nPr?
Permutations, nPr can also be represented as P(n, r), is a mathematical formula to find the number of ways to arrange r objects from n objects where order matters. The formula of P(n, r) is n! / (n − r)!. The number of permutations on a set of n elements is given by n! where "!" represents factorial. Syntax nPr = n! / (n - r)! Where: n is the total number of objects r is the number of objects to be selected ! denotes factorial Example Let's calculate P(5, ...
