Print the corner elements and their sum in a 2-D matrix in C Program.
Given a 2D matrix, the challenge is to find and print the corner elements along with their sum. In a matrix, corner elements are located at the four corners: top-left, top-right, bottom-left, and bottom-right positions. For a matrix mat[r][c] with rows from 0 to r-1 and columns from 0 to c-1, the corner elements are: mat[0][0], mat[0][c-1], mat[r-1][0], and mat[r-1][c-1]. The task is to extract these corner elements and calculate their sum. Syntax // Corner elements of a matrix mat[r][c] mat[0][0] // Top-left corner mat[0][c-1] ...
Read MoreWave effect with CSS?
The CSS wave effect is a legacy filter that was used to create sine wave distortions on elements, giving them a wavy appearance. This filter was primarily supported in Internet Explorer and is now obsolete. Modern CSS uses alternative techniques like transforms and animations to achieve wave effects.

Given four variables a, b, c, d with predefined values that represent different types of bracket pairs. The task is to use all the given brackets and print a balanced bracket expression using these bracket types. Where variables represent − a for (( b for () c for )( d for )) If we cannot form a balanced bracket expression then print "can't be formed". In case of multiple valid answers, we can print any of them. Syntax void print(int a, int b, int c, int d); Algorithm To ...

Read MoreFlip Out X Animation Effect with CSS
The CSS Flip Out X animation effect creates a 3D flipping motion where an element rotates around its horizontal (X) axis and fades out simultaneously. This animation is commonly used for exit transitions and interactive UI elements. Syntax @keyframes flipOutX { 0% { transform: perspective(400px) rotateX(0deg); opacity: 1; } 100% { transform: perspective(400px) rotateX(90deg); ...
Read MorePrint the last occurrence of elements in array in relative order in C Program.
Given an array with elements and the task is to print the last occurrences of the given elements in the list. Here we not only have to remove the duplicate elements but also we have to maintain the order of the occurrences of the elements in an array as per the last time they have occurred. For example, if we have an array of 6 elements containing some duplicate values i.e., {1, 3, 2, 3, 1, 2}, the result should be in the form of 3 1 2. Syntax void printLastOccurrence(int arr[], int n); ...
