How to use lastIndexOf () in Android textview?
This example demonstrate about How to use lastIndexOf () in Android textview.Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml. In the above code, we have taken name as Edit text, when user click on button it will take data and returns last index of “sai”.Step 3 − Add the following code to src/MainActivity.javapackage com.example.myapplication; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; ...

Read MoreC++ Program to Find Strongly Connected Components in Graphs
Weakly or Strongly Connected for a given a directed graph can be found out using DFS. This is a C++ program of this problem.Functions usedBegin Function fillorder() = fill stack with all the vertices. a) Mark the current node as visited and print it b) Recur for all the vertices adjacent to this vertex c) All vertices reachable from v are processed by now, push v to Stack End Begin Function DFS() : a) Mark the current node as visited and print it b) Recur for all the vertices adjacent to this vertex EndExample#include ...
Read MoreC++ Program to Find the Vertex Connectivity of a Graph
To find the Vertex Connectivity of a graph we need to find out Articulation Points of that graph. Articulation Points (or Cut Vertices) in a Graph is a point iff removing it (and edges through it) disconnects the graph. An articulation point for a disconnected undirected graph, is a vertex removing which increases number of connected components.AlgorithmBegin We use dfs here to find articulation point: In DFS, a vertex w is articulation point if one of the following two conditions is satisfied. 1) w is root of DFS tree and it has at least two children. ...
Read MoreC++ Program to Implement the Solovay-Strassen Primality Test to Check if a Given Number is Prime
Solovay-Strassen Primality Test is used to test a number whether it is a composite or possibly prime number.AlgorithmsBegin Declare a function modulo to the long datatype to perform binary calculation. Declare m_base, m_exp, m_mod of long datatype and pass them as a parameter. Declare two variables a, b of long datatype. Initialize a = 1, b = m_base. while (m_exp > 0) do if (m_exp % 2 == 1) then a = (a * b) % ...
Read MoreHow to convert date and time into int in Android sqlite?
Before getting into example, we should know what sqlite data base in android is. SQLite is an open source SQL database that stores data to a text file on a device. Android comes in with built in SQLite database implementation. SQLite supports all the relational database features. In order to access this database, you don't need to establish any kind of connections for it like JDBC, ODBC etc.This example demonstrate about How to convert date and time into int in Android sqliteStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all ...
Read MoreMeaning of 'const' last in a function declaration of a C++ class?
Sometimes we can find the keyword ‘const’ present at the last of function declaration. So what does it mean?Using this one function can be made as constant. The idea of constant function is that, the function cannot be modified from the objects, where they are called. It is recommended to use the constant functions in our program.Let us see one example of constant function.Example#include using namespace std; class MyClass { int value; public: MyClass(int val = 0) { value = val; } int getVal() const ...
