C++ Program to Optimize Wire Length in Electrical Circuit
This is a C++ Program to optimize Wire Length in Electrical Circuit.AlgorithmBegin Function optimizeLength() : 1) Declare a array dist[N]. 2) sptSet[i] will be true if component i is included in shortest path tree or shortest distance from src to i is finalized. 3) Initialize all distances as INFINITE and stpSet[] as false 4) Distance of source component from itself will be always 0. 5) Run a for loop cnt = 0 to N-2, Find shortest path for all components. A) Pick the minimum distance component from the set of ...

This is a C++ program to perform Optimal Paranthesization using Dynamic Programming.AlgorithmBegin Take the length n and dimension of matrix as input. MatrixChain() to find out minimum multiplications: Arguments: a[i][j]=Minimum number of scalar multiplications needed to compute the matrix A[i]A[i+1]...A[j] = A[i..j] where dimension of A[i] is p[i-1] x p[i]. a[i][j] means cost is zero when multiplying one matrix. L is chain length. m = cost / scalar multiplications. Body of the function: for i = ...

This is a C++ program to find Basis and Dimension of a Matrix.AlgorithmBegin Function determinant() : It calculates determinant of the matrix. /* Arguments: n = number of elements. matrix[10][10] = input matrix. */ declare the submatrix submatrix[10][10]. //Body of the function: if (n == 2) return ((matrix[0][0] * matrix[1][1]) - (matrix[1][0] * matrix[0][1])) else Make a for loop c = 0 to n-1 Declare and initialize submati = 0, submatj. ...
Read MoreHow many types of JDBC Drivers are there?
There are 4 types of JDBC drivers namely, Type-1, Type-2, Type-3 and, Type-4.Type1 It is the ODBC − JDBC bridge driver, it acts as a bridge between JDBC and, ODBC database connectivity mechanism. Using this you can access the databases which support only ODBC. Initially, it is used extensively, since most of the databases supported only ODBC.Whenever Java application sends a request to the JDBC-ODBC bridge driver the request internally calls the ODBC equivalent function and the ODBC driver retrieves the result from the underlying database and sends it back to the JDBC-ODBC bridge driver.Advantages of type1 driverFollowing are the advantages ...
Read MoreIterate through Quintet class in Java Tuples
You can iterate through Quintet class using a loop, like arrays in Java.Let us first see what we need to work with JavaTuples. To work with Quintet class in JavaTuples, you need to import the following package −import org.javatuples.Quintet;Note − Steps to download and run JavaTuples program If you are using Eclipse IDE to run Quintet Class in JavaTuples, then Right Click Project → Properties → Java Build Path → Add External Jars and upload the downloaded JavaTuples jar file.The following is an example −Exampleimport org.javatuples.Quintet; public class Demo { public static void main(String[] args) { ...
Read MoreJava Program to get Temporal Queries precision
To get Temporal Queries precision, use the TemporalQuery interface with the precision() method of the TemporalQueries −TemporalQueryprecision = TemporalQueries.precision(); Get the precision for LocalDate: LocalDate.now().query(precision) Get the precision for LocalTime: LocalTime.now().query(precision) Get the precision for YearMonth: YearMonth.now().query(precision) Get the precision for Year: Year.now().query(precision)Exampleimport java.time.LocalDate; import java.time.LocalDateTime; import java.time.LocalTime; import java.time.Year; import java.time.YearMonth; import java.time.temporal.TemporalQueries; import java.time.temporal.TemporalQuery; import java.time.temporal.TemporalUnit; public class Demo { public static void main(String[] args) { TemporalQueryprecision = TemporalQueries.precision(); System.out.println("TemporalQueries precision..."); System.out.println(LocalDate.now().query(precision)); System.out.println(LocalTime.now().query(precision)); System.out.println(LocalDateTime.now().query(precision)); System.out.println(YearMonth.now().query(precision)); System.out.println(Year.now().query(precision)); ...
Read MoreHow do I discover the Quarter of a given Date in Java?
Let us first get the current date −LocalDate currentDate = LocalDate.now();Now, use the Calendar class and set the locale −Calendar cal = Calendar.getInstance(Locale.US);Now, get the month −int month = cal.get(Calendar.MONTH);Find the Quarter −int quarter = (month / 3) + 1;Exampleimport java.time.LocalDate; import java.util.Calendar; import java.util.Locale; public class Demo { public static void main(String[] args) { LocalDate currentDate = LocalDate.now(); System.out.println("Current Date = "+currentDate); Calendar cal = Calendar.getInstance(Locale.US); int month = cal.get(Calendar.MONTH); int quarter = (month / 3) + 1; System.out.println("Quarter = "+quarter); } }OutputCurrent Date = 2019-04-12 Quarter = 2
Read MoreHow to get number of quarters between two dates in Java
Let’s say we have the following two dates −LocalDate.of(2019, 3, 20); LocalDate.of(2019, 10, 25);To get the number of quarters between the above two dates, use the QUARTER_YEARS −IsoFields.QUARTER_YEARS.between(LocalDate.of(2019, 3, 20),LocalDate.of(2019, 10, 25));Exampleimport java.time.LocalDate; import java.time.temporal.IsoFields; public class Demo { public static void main(String[] args) { long quarters = IsoFields.QUARTER_YEARS.between(LocalDate.of(2019, 3, 20), LocalDate.of(2019, 10, 25)); System.out.println("Quarters between the two dates = " + quarters); } }OutputQuarters between the two dates = 2
