In this problem, we are given a linked list with a value, link pointer and an arbitrary pointer. Our task is to make the arbitrary pointer point to point the largest value which is on the right side of it in the linked list.Let’s take an example to understand the problem, Here, we can see the following arbitrary pointers of the linked list, which points to the greatest elements on the right side of the linked list.12 -> 76, 76 -> 54, 54 -> 8, 8 -> 41To solve this problem, we need to find the greatest element to the ...

We are given the variable and the task is to find the probability of the variable using an error function available in C++ STL. This function is available in the cmath header file in C++.What is an Error function?Error function in mathematics is also known as Gauss error function which is denoted by erf(). It is a special function that is used in probability, statistic and partial differential equations for the calculation of error that can occur. It is defined as −There are two closely related error function −complementary error function − It is defined as erfc x = 1 ... Read More
Computer graphics deals with drawing images and graphics on a computer screen. Here, we treat the screen as a 2-D coordinate system. This coordinate system starts from top-left (0, 0) and ends at bottom-right.Viewing plane is the area defined for drawing graphics in computer graphics. Or the visible area of the screen.Clipping is deleting those points or graphics that are outside the viewing plane.Let's take an example to understand clipping.Here points C and D will be clipped as they are outside the viewing plane marked with blue color.In order to clip a point in computer graphics. We need to know ... Read More
