How to use trim () in Android textview?
This example demonstrate about How to use trim () 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 trim the data without spaces.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 ...

In this Program we will basically find a feedback arc set which contains edges which when removed from the graph, graph becomes directed acyclic graph.AlgorithmBegin function checkCG(int n) : n: number of vertices. arr: struct graph variable. Initialize cnt = 0 and size = (n-1). For i =0 to n-1 if (cnt == size) return 0 if (arr[i].ptr == NULL) Increase cnt. for j = 0 to n-1 while (arr[j].ptr != NULL) if ((arr[j].ptr)->des == (arr[i].ptr)->des) ...

Weakly or Strongly Connected for a given a undirected 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 Generate Randomized Sequence of Given Range of Numbers
At first let us discuss about the rand() function. rand() function is a predefined method of C++. It is declared in header file. rand() is used to generate random number within a range. Here min_n is the minimum range of the random numbers and max_n is the maximum range of the numbers. So rand() will return the random numbers between min_n to (max_n – 1) inclusive of the limit values. Here if we mention lower and upper limits as 1 and 100 respectively, then rand() will return values from 1 to (100 – 1). i.e. from 1 to 99.AlgorithmBegin ...
Read MoreHow to use upper () 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 use upper () in Android sqliteStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to ...

The Baillie-PSW Primality Test, this test named after Robert Baillie, Carl Pomerance, John Selfridge, and Samuel Wagstaff. It is a test which tests whether a number is a composite number or possibly prime.AlgorithmMillerTest()Begin Declare a function MillerTest of Boolean type. Declare MT_dt and MT_num of integer datatype and pass as the parameter. Declare MT_a and MT_x of integer datatype. Initialize MT_a = 2 + rand( ) % (MT_num - 4). Initialize MT_x = pow(MT_a, MT_dt, MT_num). if (MT_x == 1 || MT_x == MT_num - 1) then ...

Read MoreWhat is an unsigned char in C++?
In C++ we have seen there is character type data called char. Sometimes we have seen unsigned char also. So here we will see what is basically the unsigned char means. What are the basic differences between signed char and unsigned char?Signed char and unsigned char both are used to store single character. The variable stores the ASCII value of the characters. For an example if ‘A’ is stored, actually it will hold 65. For signed char we need not to write the signed keyword. But for unsigned, we have to mention the keyword. The syntax is like below.unsigned char ...
Read MoreWhat are __FILE__, __LINE__, and __FUNCTION__ in C++
Here we will see what are the __FILE, __LINE__ and __FUNCTION__ in C++.The __FILE__This macro is used to get the path of the current file. This is useful when we want to generate log files. The following code will explain its functionality.Example#include using namespace std; int errorLog (const char* file, const std::string& msg){ cerr
