BartSMP [9]

Using the knowledge in computational language in JAVA it is possible to write the code being methods define a method named getWordFrequency that takes an array of strings

<h3>Writting the code in JAVA:</h3>

import java.util.*;

public class WordFrequency {

public static int getWordFrequency(String[] wordsList , int listSize , String currWord) {

HashMap<String , Integer> hm = new HashMap<>();

for(String st : wordsList) {

String str = st.toLowerCase();

hm.put(str, hm.getOrDefault(str, 0) + 1);

}

for(String st : wordsList) {

String str = st.toLowerCase();

System.out.println(st + " " + hm.get(str));

}

String currWordToLowerCase = currWord.toLowerCase();

return hm.get(currWordToLowerCase);

}

public static void main(String[] args) {

// TODO Auto-generated method stub

String[] wordsList = {"hey" , "Hi" , "Mark" , "hi" , "mark"};

int listSize = wordsList.length;

String currWord = "hey";

System.out.println("The frequency of " + currWord + " is : " + getWordFrequency(wordsList , listSize , currWord));

}

}

Syntax:

=SUMIFS (sum_ranges, range_1, criteria_1, [range_2], [criteria_2], ...)

In the above syntax, we use 5 arguments in function that can be defined as:

The sum_range argument is used to sum of range to be summed.
The range_1 and range_2 arguments are stands for first and second ranges for evaluating. In which the range_2 can be optional.

The strongest normal form that R=AB is in is? a. not known since we don't know the set of functional dependencies b. 2nf c. 3nf

Firlakuza [10]

A correct option is option (a). The strongest normal form that R=AB is in is not known since we don't know the set of functional dependencies

What are functional dependencies?

An association between two attributes, often the PK and other non-key properties in a database, is known as a functional dependency (FD). If the value of attribute X (often the PK) impacts the value of attribute Y in a unique way for each valid instance of X, then attribute Y is functionally dependent on attribute X for any relation R.

How do you identify functional dependency?

When two different values of B are related to the same A, this is known as a "functional dependency" A->B.
A key must be distinct, therefore even if two tuples contain the same value for one or more attributes, the key values must differ.
