The place value can be used to convert a binary number, such as 11010010, into decimal form: 11010010 = 1 x 27 + 1 x 26 + 0 x 25 +1 x 24.In light of the aforementioned, the base-4 number system has 4 digits: 0, 1, 2, and 3. Any 2-bit number can be represented by a single base-4 integer since a 2-bit number can only represent one of the values 0, 1, 2, or 3.

<h3>What does base 4 mean?</h3>
  • Base-4 is a quaternary  number system. Any real number is represented by the digits 0, 1, 2, and 3.
  • In light of the aforementioned, the base-4 number system has 4 digits: 0, 1, 2, and 3. Any 2-bit number can be represented by a single base-4 integer since a 2-bit number can only represent one of the values 0, 1, 2, or 3.
  • The four digits of Quaternary (Base 4) are 0 through 3.
  • Binary code 4 is 100. In a binary number system, we only use the digits 0 and 1 to represent a number, as opposed to the decimal number system, which uses the digits 0 to 9. (bits).

Write a public member function which replace that replaces one occurrence of a given item in the ArrayBag with another passed as
ira [324]

Answer:

The method is written in Java

public static boolean abc(int [] ArrayBag,int num, int replace){

    Boolean done = false;

    for(int i =0; i<ArrayBag.length;i++){

        if(ArrayBag[i] == num){

            ArrayBag[i] = replace;

            done = true;

        }

    }

    for(int i = 0;i<ArrayBag.length;i++){

        System.out.println(ArrayBag[i]+" ");

    }

    return done;

}

Explanation:

The method is written in java

The arguments of the method are:

<em>1. ArrayBag -> The array declares as integer</em>

<em>2. num -> The array element to check the presence</em>

<em>3. replace - > The replacement variable</em>

This line defines the method as boolean.

public static boolean abc(int [] ArrayBag,int num, int replace){

This line declares a boolean variable as false

    Boolean done = false;

The following iterates through the elements of the array

    for(int i =0; i<ArrayBag.length;i++){

This checks if the array element exist

        if(ArrayBag[i] == num){

If yes, the array element is replaced

            ArrayBag[i] = replace;

The boolean variable is updated from false to true

            done = true;

        }

    }

The following iteration prints the elements of the array

<em>     for(int i = 0;i<ArrayBag.length;i++){</em>

<em>         System.out.println(ArrayBag[i]+" ");</em>

<em>     }</em>

This prints returns the boolean thats indicates if replacement was done or not.

    return done;

}

<em>Attached to this solution is the program source file that includes the main method of the program</em>
