AA Trees in C/C++?
An AA tree in computer science is defined as a form of balanced binary search tree designed for storing and retrieving ordered data efficiently. AA trees are a variation of red-black trees but with simplified balancing rules. Unlike red-black trees, red nodes (horizontal links) in AA trees can only exist as right children, never left children. Key Properties AA trees maintain the following invariants − The level of every leaf node is one The level of every left child is exactly one smaller than its parent The level of every right child is equal to or ...
Read MoreSelects every element whose href attribute value ends with ".htm" with CSS
The CSS [attribute$="value"] selector targets elements whose specified attribute value ends with a particular string. In this case, we're selecting elements whose href attribute ends with ".htm". Syntax [attribute$="value"] { /* CSS properties */ } Example The following example selects all anchor elements whose href attribute ends with ".htm" and applies orange border styling − [href$=".htm"] { border: 5px solid ...

A sticky navbar is a navigation bar that sticks to a specific position on the page when scrolling. To create a sticky navbar, use the position: sticky property along with the top property to define where it should stick. Syntax selector { position: sticky; top: value; } Example The following example creates a sticky navbar that remains at the top of the viewport when scrolling − body { ...
Read MoreA-Buffer Method in C/C++?
The A-Buffer method is an advanced hidden surface removal technique in computer graphics that extends the traditional Z-Buffer algorithm. Also known as anti-aliased, area-averaged, or accumulation buffer, this technique handles both opaque and transparent objects, making it suitable for complex rendering scenarios where multiple surfaces contribute to a single pixel. Syntax struct ABuffer { float depth; union { struct { int r, g, b; ...
Read MoreCSS transition-timing-function property
The CSS transition-timing-function property specifies the speed curve of the transition effect. It controls how intermediate values are calculated during a transition, determining whether the animation starts slowly and speeds up, or starts quickly and slows down. Syntax selector { transition-timing-function: value; } Possible Values ValueDescription linearConstant speed from start to end easeSlow start, fast middle, slow end (default) ease-inSlow start, then speeds up ease-outFast start, then slows down ease-in-outSlow start and end, fast middle cubic-bezier()Custom timing function using cubic bezier curve Example: Different Timing Functions ...
Read MoreSet the name of the CSS property the transition effect is for
The CSS transition-property property specifies which CSS property should have a transition effect applied to it. This property determines which property changes will be animated when the element's state changes. Syntax selector { transition-property: property-name; } Possible Values ValueDescription noneNo transition effect will be applied allAll properties that can be animated will have transition effects (default) property-nameSpecific CSS property name like width, height, background-color, etc. initialSets the property to its default value inheritInherits the value from parent element Example: Width Transition The following example demonstrates a ...
Read MoreA Number Link Game in C/C++?
The Number Link Game is a logic puzzle played on an n × n grid. Some squares are empty, some are solid (blocked), and some contain numbered endpoints (1, 2, 3, etc.). Each number appears exactly twice on the board. The goal is to connect matching numbers with non-intersecting paths using only horizontal and vertical movements, filling all non-solid squares. Syntax // Union-Find structure for path generation typedef struct { int parent[MAX_SIZE]; int rank[MAX_SIZE]; } UnionFind; // Game board representation typedef struct { int ...
Read MoreCSS transition-duration property
The CSS transition-duration property is used to set the duration of CSS transitions. It specifies how long a transition takes to complete when an element changes from one state to another. Syntax selector { transition-duration: time; } Possible Values ValueDescription timeDuration in seconds (s) or milliseconds (ms) 0sNo transition (default) inheritInherits from parent element Example: Basic Transition Duration The following example demonstrates a 2-second transition duration on hover − .box { ...
Read MoreSet a delay for the CSS transition effect
The CSS transition-delay property is used to specify a delay before a transition effect begins. This allows you to control when the transition starts after the trigger event occurs. Syntax selector { transition-delay: time; } Possible Values ValueDescription timeSpecifies the delay in seconds (s) or milliseconds (ms) 0No delay (default) Example The following example demonstrates a 2-second delay before the width transition begins − div { width: 150px; ...
Read MoreSystem() Function in C/C++
The system() function is a part of the C standard library that executes system commands. It is used to pass commands that can be executed in the command processor or terminal of the operating system, and returns the command's exit status after completion. Note: To use the system() function, include header file. Syntax int system(const char *command); Parameters command − A pointer to a null-terminated string containing the command to be executed. If NULL, checks if command processor is available. Return Value Returns the exit ...
