Dynamic ArrayIn python, a list, set and dictionary are mutable objects. While number, string, and tuple are immutable objects. Mutable objects mean that we add/delete items from the list, set or dictionary however, that is not true in case of immutable objects like tuple or strings.In python, a list is a dynamic array. Let's try to create a dynamic list −>>> #Create an empty list, named list1 >>> list1 = [] >>> type (list1) Add some items onto our empty list, list1 −>>> # Add items >>> list1 =[2, 4, 6] >>> list1 [2, 4, 6] >>> # Another way ...

To extract the Day/Month/Year from a timestamp, you need to use the date_parse() function. The syntax as follows −print_r(date_parse(“anyTimeStampValue”));The PHP code is as follows −$yourTimeStampValue="2019-02-04 12:56:50"; print_r(date_parse($yourTimeStampValue));The snapshot of PHP code is as follows −The following is the output −Array ( [year] => 2019 [month] => 2 [day] => 4 [hour] => 12 [minute] => 56 [second] => 50 [fraction] => 0 [warning_count] => 0 [warnings] => Array ( ) [error_count] => 0 [errors] => Array ( ) [is_localtime] => )The snapshot of the sample output −
The z format means General Time Zone. We will use it like this.SimpleDateFormat("z");Let us see an example −// displaying timezone in z format SimpleDateFormat simpleformat = new SimpleDateFormat("z"); String strTimeZone = simpleformat.format(new Date()); System.out.println("TimeZone in z format = "+strTimeZone);Above, we have used the SimpleDateFormat class, therefore the following package is imported −import java.text.SimpleDateFormat;The following is an example −Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { // displaying current date and time Calendar ...

Whenever you want all the values like not null for a column then use count(*). This is faster than using count() method.The syntax to use count(*) is as follows −select count(*) as anyVariableName from yourTableName;To understand the above concept, let us first create a table. The query to create a table is as follows −mysql> create table CountingDemo -> ( -> BookId int -> ); Query OK, 0 rows affected (0.60 sec)Insert some records in the table using insert command. The query is as follows −mysql> insert into CountingDemo values(100); Query OK, 1 row affected (0.13 sec) ... Read More
In this program we will see how to find the largest number from a block of bytes using 8085.Problem StatementWrite 8085 Assembly language program to find the largest number from a block of bytes.DiscussionIn this program the data are stored at location 8001H onwards. The 8000H is containing the size of the block. After executing this program, it will return the largest number and store it at location 9000H.Logic is simple, we are taking the first number at register B to start the job. In each iteration we are getting the number from memory and storing it into register A. ... Read More
Use the zzzz format like this for TimeZone.SimpleDateFormat("zzzz");Let us see an example −// displaying timezone in zzzz format simpleformat = new SimpleDateFormat("zzzz"); String strTimeZone = simpleformat.format(new Date()); System.out.println("TimeZone in zzzz format = "+strTimeZone);Above, we have used the SimpleDateFormat class, therefore the following package is imported −import java.text.SimpleDateFormat;The following is an example −Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { // displaying current date and time Calendar cal = Calendar.getInstance(); ...

Instead of simulating an array variable, use temporary table in MySQL. The syntax is as follows −create temporary table if not exists yourTemporaryTableName select yourColumnName1, yourColumnName2, ......N from yourTableName where conditionTo understand the above syntax, let us first create a table. The query to create a table is as follows −mysql> create table SimulateArrayDemo -> ( -> Id int, -> FirstName varchar(100), -> LastName varchar(100 -> ) -> ); Query OK, 0 rows affected (1.25 sec)Insert some records in the table using ...

Quantum figuring contemplates hypothetical calculation frameworks (quantum PCs) that make coordinate utilization of quantum-mechanical marvels, for example, superposition to perform operations on data. Quantum PCs are unique in relation to binary digital PCs in light of transistors.While regular advanced registering requires that the information is encoded into twofold digits (bits), each of which is dependable in one of two distinct states (0 or 1), quantum calculation utilizes quantum bits, which can be in superpositions of states. A Quantum Turing Machine is a hypothetical model of such a PC and is otherwise called the general quantum PC.What are they?Starting at 2017, ... Read More

In this program we will see how to add two 16-bit numbers.Problem StatementWrite8085 Assembly language program to add two 16-bit number stored in memory location 8000H – 8001H and 8002H – 8003H.DiscussionIn this program we are pointing the operand addresses using HL and DE register pair. Then adding LSBytes by ADD operator, and after that adding MSBytes using ADC operator to consider the carry flag result. The 16-bit result will be stored at BC register, and by checking the carry bit after addition we can simply put 1 into memory.We are taking two numbersBCAD + FE2D = 1BADAInputAddressData......8000AD8001BC80022D8003FE......Flow DiagramProgramAddressHEX CodesLabelsMnemonicsCommentsF00021, ...
