In this program, we will see how to find the square of an 8-bit number.Problem StatementWrite 8085 Assembly language program to find the square of a number The number is stored at location 8000H, store the result at 8050H.DiscussionIn 8085, we cannot perform the multiplication operation directly. We are performing the multiplication by using repetitive addition. To get square of a number, we have to multiply the number with itself.InputAddressData……80000C……Flow Diagram ProgramAddressHEX CodesLabelsMnemonicsCommentsF00021, 00, 80 LXI H, 8000HLoad the number from 8000HF003AF XRA AClear accumulatorF00446 MOV B, MLoad data from memory to BF00586LOOPADD MAdd memory byte with AF00605 DCR BDecrease B by 1F007C2, 05, F0 JNZ ...

Self-Organizing list basically updates the list of given range of items on the basis of last searched item. In this method, the sequential searching approach is used. This algorithm shifts the more important data to the beginning of the list. The time complexity of this search technique is O(n).AlgorithmBegin Function FibonacciSearch(). Calculate the mid value using ‘start+fib[index-2]’ expression. If the chosen item is equal to the value at mid index, print result and return to main. If it is lesser than the value at mid index, proceed with the left sub-array. If it is more ... Read More
If you want to delete all documents from the collection, you can use deleteMany(). Let us first create a collection and insert some documents to it:> db.deleteDocumentsDemo.insert({"Name":"Larry", "Age":23}); WriteResult({ "nInserted" : 1 }) > db.deleteDocumentsDemo.insert({"Name":"Mike", "Age":21}); WriteResult({ "nInserted" : 1 }) > db.deleteDocumentsDemo.insert({"Name":"Sam", "Age":24}); WriteResult({ "nInserted" : 1 })Now display all the documents from the collection. The query is as follows:> db.deleteDocumentsDemo.find().pretty();The following is the output:{ "_id" : ObjectId("5c6ab0e064f3d70fcc914805"), "Name" : "Larry", "Age" : 23 } { "_id" : ObjectId("5c6ab0ef64f3d70fcc914806"), "Name" : "Mike", "Age" : 21 } { "_id" : ObjectId("5c6ab0f864f3d70fcc914807"), "Name" ...

A JSP expression element contains a scripting language expression that is evaluated, converted to a String, and inserted where the expression appears in the JSP file.Because the value of an expression is converted to a String, you can use an expression within a line of text, whether or not it is tagged with HTML, in a JSP file.The expression element can contain any expression that is valid according to the Java Language Specification but you cannot use a semicolon to end an expression.Following is the syntax of JSP Expression −You can write the XML equivalent of the above syntax as ...

The tag is used to parse numbers, percentages, and currencies.AttributeThe tag has the following attributes −AttributeDescriptionRequiredDefaultValueNumeric value to read (parse)NoBodytypeNUMBER, CURRENCY, or PERCENTNonumberparseLocaleLocale to use when parsing the numberNoDefault localeintegerOnlyWhether to parse to an integer (true) or floating-point number (false)NofalsepatternCustom parsing patternNoNonetimeZoneTime zone of the displayed dateNoDefault time zonevarName of the variable to store the parsed numberNoPrint to pagescopeScope of the variable to store the formatted numberNopageA pattern attribute is provided that works just like the pattern attribute for the tag. However, in the case of parsing, the pattern attribute tells the parser what format to expect.Example ... Read More
An immutable copy of a LocalTime object where some nanoseconds are subtracted from it can be obtained using the minusNanos() method in the LocalTime class in Java. This method requires a single parameter i.e. the number of nanoseconds to be subtracted and it returns the LocalTime object with the subtracted nanoseconds.A program that demonstrates this is given as follows −Example Live Demoimport java.time.*; public class Demo { public static void main(String[] args) { LocalTime lt = LocalTime.now(); System.out.println("The current LocalTime is: " + lt); System.out.println("The LocalTime with 1000 nanoseconds subtracted is: ...

Natural language processing is the study of automated generation and understanding of natural human languages. This is becoming more and more interesting tasks to solve, as computer technology is integrated into almost every industry nowadays. We are going to study one specific field within natural language processing; readability. This involves the topic of determining the readability of a text. This indicates how difficult it is to read or understand a text.A readability index is a numeric value that indicates how difficult (or easy) it is to read and understand a text. There are several different tests for determining readability, and ... Read More
You can use $all operator to find by multiple array items. To understand the concept, let us create a collection with the document.The query to create a collection with a document is as follows −> db.findByMultipleArrayDemo.insertOne({"StudentFirstName":"John", "StudentLastName":"Smith", "StudentCoreSubject":["Compiler", "Operating System", "Computer Networks"]}); { "acknowledged" : true, "insertedId" : ObjectId("5c7ef07b559dd2396bcfbfc4") } > db.findByMultipleArrayDemo.insertOne({"StudentFirstName":"Carol", "StudentLastName":"Taylor", "StudentCoreSubject":["MongoDB", "MySQL", "SQL Server"]}); { "acknowledged" : true, "insertedId" : ObjectId("5c7ef09d559dd2396bcfbfc5") } > db.findByMultipleArrayDemo.insertOne({"StudentFirstName":"Bob", "StudentLastName":"Taylor", "StudentCoreSubject":["MongoDB", "MySQL", "SQL Server"]}); { "acknowledged" : true, "insertedId" : ObjectId("5c7ef0c7559dd2396bcfbfc6") } > db.findByMultipleArrayDemo.insertOne({"StudentFirstName":"David", "StudentLastName":"Johnson", "StudentCoreSubject":["Compiler", "Operating System", "Computer Networks"]}); { ...

You can use COUNT() function for this. Let us first create a demo tablemysql> create table countValueDemo -> ( -> ShippingDatetime datetime, -> FirstValue int, -> SecondValue int -> ); Query OK, 0 rows affected (1.35 sec)Insert some records in the table using insert command. The query is as follows −mysql> insert into countValueDemo values('2019-01-23', 1, 2); Query OK, 1 row affected (0.24 sec) mysql> insert into countValueDemo values('2017-02-21', NULL, 2); Query OK, 1 row affected (0.13 sec) mysql> insert into countValueDemo values('2016-04-12', 1, NULL); ...
