It styles elements when they have no siblings, making it useful for applying special formatting to isolated elements. Syntax element:only-child { property: value; } Example: Styling Only Child Paragraphs The following example demonstrates how the :only-child selector applies styles only to paragraphs that are the sole child of their parent − p:only-child { background-color: orange; ...

Given a positive integer n, we have to print all the subsets of the set {1, 2, 3, 4, … n} without using any array or loops. For example, if n = 3, we need to print all subsets of {1, 2, 3} which are {1 2 3}, {1 2}, {2 3}, {1 3}, {1}, {2}, {3}, and { }. Since we cannot use loops or arrays, recursion is the only way to solve this problem. We use binary representation to generate subsets efficiently. Syntax void generateSubsets(int n, int currentNum); void printSubset(int bitPosition, int num, int ...

CSS 3D transforms allow you to manipulate elements in three-dimensional space using the transform property. These methods enable translation, rotation, and scaling along the x, y, and z axes to create depth and perspective effects. Syntax selector { transform: transform-function(values); transform-style: preserve-3d; /* Optional: preserves 3D space for child elements */ } 3D Transform Methods MethodDescription matrix3d(n, n, n, n, n, n, n, n, n, n, n, n, n, n, n, n)Transforms element using 16 values of a 4x4 matrix translate3d(x, y, z)Moves element along ...

Radio frequency (RF) is the oscillation of an A.C. current or voltage in the frequency range of 20KHz to 300 GHz. In C programming, we can create programs to classify and work with different RF bands. Radio frequency spectrum is divided into bands − frequency ranges used for specific applications. Each band has distinct characteristics, propagation methods, and uses in communication systems. Syntax // Basic structure for RF band classification if (frequency >= min_freq && frequency = 3000 && freqHz = 30000 && freqHz = 300000 && freqHz = 3000000 && freqHz = 30000000 && freqHz = 300000000 && freqHz = 3000000000 && freqHz = 30000000000 && freqHz

The CSS rotateX() function is used to rotate an element around its X-axis in 3D space. This creates a horizontal rotation effect, making the element appear to flip vertically. Syntax selector { transform: rotateX(angle); } The angle value can be specified in degrees (deg) or radians (rad). Example The following example demonstrates X-axis 3D rotation by comparing a normal element with a rotated one − div { width: 200px; ...
