Here we shall discuss a C++ program to find the Longest Subsequence Common to All Sequences in a Set of Sequences.AlgorithmsBegin Take the array of strings as input. function matchedPrefixtill(): find the matched prefix between string s1 and s2 : n1 = store length of string s1. n2 = store length of string s2. for i = 0, j = 0 to i
Html taga) The tag is used to define a client-side script.b) The tag contains scripting statements or an external script file.JavaScript code must be keep in script tag.Let's see the use of the tag. For suppose declare the variable outside the script tag. Live DemoExample var a = 1; var b = 2; var c = a + b; document.getElementById("tag").innerHTML = c; Outputvar a = 1For suppose, let the variable be declared inside the script tag. Live DemoExample var a = 1; var b = 2; var c = a + b; document.getElementById("tag").innerHTML = c; Output3
Position buttons vertically one after another using the Box class. Use the createVerticalBox() method that displays components from top to bottom −JButton button1 = new JButton("One"); JButton button2 = new JButton("Two"); JButton button3 = new JButton("Three"); Box box = Box.createVerticalBox(); box.add(button1); box.add(button2); box.add(button3);The following is an example to position buttons vertically one after another −Examplepackage my; import javax.swing.Box; import javax.swing.JButton; import javax.swing.JFrame; public class SwingDemo { public static void main(String[] args) { JButton button1 = new JButton("One"); JButton button2 = new JButton("Two"); JButton button3 = new JButton("Three"); ...

To concatenate two tables, UNION ALL in MySQL. Let us create a table −mysql> create table DemoTable1 ( Id int, FirstName varchar(20) ); Query OK, 0 rows affected (1.52 sec)Insert some records in the table using insert command −mysql> insert into DemoTable1 values(10, 'John'); Query OK, 1 row affected (0.28 sec) mysql> insert into DemoTable1 values(20, 'Carol'); Query OK, 1 row affected (0.28 sec)Display all records from the table using select statement −mysql> select *from DemoTable1;Output+------+-----------+ | Id | FirstName | +------+-----------+ | 10 | John | ...

PointersPointers are used to store the address of variable.SyntaxType *pointer;InitializationType *pointer; Pointer = variable name;Functionspointers are used to store address of variable.pointers can have a null value assigned.pointer can be referenced by pass by reference.a pointer has its own memory address and size on the stack.Example Live Demo#include using namespace std; int main() { // A normal integer variable int a = 7; // A pointer variable that holds address of a. int *p = &a; // Value stored is value of variable "a" cout
In Java you can copy an object in several ways, among them, copy constructor and the clone method are the mostly used.Using copy constructorGenerally, the copy constructor is a constructor which creates an object by initializing it with an object of the same class, which has been created previously. Java does support for copy constructors but you need to define them yourself.ExampleIn the following Java example, we a have a class with two instance variables name and age and a parameterized constructor initializing these variables.Then, we have another constructor which accepts an object of the current class and initializes the ...

In C++, we can overload the functions. But sometimes the overloading is not done. In this section, we will see what are the different cases, in which we cannot overload the functions.When function signatures are same, only the return type is different, then we cannot overload the function.int my_func() { return 5; } char my_func() { return 'd'; }When the member functions have the same name and same parameter list in a class, then they cannot be overloaded.class My_Class{ static void func(int x) { //Something } void func(int x) { ...

Here we shall discuss a C++ Program to find number of ways to Partition a word in such a way that each word is a Palindrome.AlgorithmsBegin Take the word as input. Function partitionadd(vector &u, string &s, vector &tmp, int index): if (index == 0) tmp.clear() for i = index to length-1 st = st + s[i] if (checkPalin(st)) tmp.push_back(st) if (i+1 < length) partitionadd(u, s, tmp, i+1) else ...
