Consider we have few elements in a linked list. We have to find the multiplication result of last n number of elements. The value of n is also given. So if the list is like [5, 7, 3, 5, 6, 9], and n = 3, then result will be 5 * 6 * 9 = 270.The process is straight forward. We simply read the current element starting from left side, then add the elements into stack. After filling up the stack, remove n elements and multiply them with the prod. (initially prod is 1), when n number of elements are ... Read More

The CharEnumerator.Dispose() method in C# is used to release all resources used by the current instance of the CharEnumerator class.Syntaxpublic void Dispose ();Let us now see an example to implement the CharEnumerator.Dispose() method −Exampleusing System; public class Demo { public static void Main(){ string strNum = "356"; CharEnumerator ch = strNum.GetEnumerator(); while (ch.MoveNext()) Console.Write(ch.Current + " "); // disposed ch.Dispose(); // this will show an error since we disposed the object above // Console.WriteLine(ch.Current); } }OutputThis will produce the following output −3 5 6

The CharEnumerator.Clone() method in C# is used to create a copy of the current CharEnumerator object.Syntaxpublic object Clone();Let us now see an example to implement the CharEnumerator.Clone() method −Exampleusing System; public class Demo { public static void Main(){ string strNum = "356"; CharEnumerator ch = strNum.GetEnumerator(); while (ch.MoveNext()){ Console.Write(ch.Current + " "); CharEnumerator enumClone = (CharEnumerator)ch.Clone(); while (enumClone.MoveNext()) Console.Write(enumClone.Current + " "); Console.WriteLine(); } } }OutputThis will produce the following output −3 5 6 5 6 6

Consider we have few elements in a linked list. We have to find the multiplication result of first k number of elements. The value of k is also given. So if the list is like [5, 7, 3, 5, 6, 9], and k = 3, then result will be 5 * 7 * 3 = 105.The processes is straight forward. We simply read the current element starting from left side, then multiply it with the prod. (initially prod is 1), when k number of elements are traversed, then stop.Example#include #include using namespace std; class Node{ public: ... Read More

Suppose we have the diameter and the height of the cylinder, we have to find the perimeter of the cylinder. As the perimeter is the outline of two dimensional object, then we cannot find the perimeter of one three dimensional object directly. We can make a cross section of the cylinder, and convert it as rectangle, then find the perimeter. The two sides of the rectangular cross section are the diameter, and the height. So perimeter is −p=(2*d)+(2*h)Example#include using namespace std; int getCylinderPerimeter(int d, int h) { return (2*d) + (2*h); } int main() { int diameter = ... Read More
