If classes C1 and C2 both implement an interface Cint, which has a method whichIsIt, and if C1 c = new C1( ); is performed at on

Assoli18 [71]

Answer:

FALSE

Explanation:

Because C1 and C2 implement the same interface, they both implement whichIsIt. The variable c is known as a polymorphic variable, meaning that it can change from being an C1 to a C2. So, the message c.whichIsIt( ); may invoke C1's whichIsIt or C2's whichIsIt. This can only be known at runtime.

Ira Lisetskai [31]

Answer: Hello your question lacks some details attached below is the missing detail

answer :

a) True , B) False C) True D) True

Explanation:

a) True ; The critical section cannot be executed by more than one process at a time

b) False : The code does not satisfy the progress condition, because while loops are same hence no progress

c ) True : The code satisfies the bounded waiting condition, because of the waiting condition of the while loop

d) True : No matter how many times this program is run, it will always produce the same output, this is because of the while loop condition

Write a method that takes three numerical String values and sums their values.

Sphinxa [80]

Answer:

<u>Algorithm</u>:

Take a int variable c=0.
Run the loop from 0 to String length.
Get the each index value using charAt() method which will return the char value.
Convert that char into int by typecasting or any other way.
Now check that ASCII fall into the range of 48-57 for 0-9 int number.
If it matches then first convert that number into integer using Integer.parseInt().
Then add with the c and store to the same variable i.e c.
Repeat from 3-7 till the end of the loop.
At the end of loop , Print c outside the loop.

Explanation:

// Java program to calculate sum of all numbers present

// in a string containing alphanumeric characters

class GFG

{

// Function to calculate sum of all numbers present

// in a string containing alphanumeric characters

static int findSum(String str)

{

// A temporary string

String temp = "";

// holds sum of all numbers present in the string

int sum = 0;

// read each character in input string

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

{

char ch = str.charAt(i);

// if current character is a digit

if (Character.isDigit(ch))

temp += ch;

// if current character is an alphabet

else

{

// increment sum by number found earlier

// (if any)

sum += Integer.parseInt(temp);

// reset temporary string to empty

temp = "0";

}

// atoi(temp.c_str()) takes care of trailing

// numbers

return sum + Integer.parseInt(temp);

}

// Driver code

public static void main (String[] args)

{

// input alphanumeric string

String str = "1abc5yz7";

System.out.println(findSum(str));

}

Let T(n) denote the running time for the Sort-and-Count algorithm (below). Sort-and-Count(L) { if list L has one element return

butalik [34]

Answer:

The answer is " $\bold{T(n) = 2T(\frac{n}{2}) + n}$ "

Explanation:

Given:

The Merge-And-Count of (A,B) runs in time |Al+IB|

T(n) recurrence=?

Calculating the value of the recurrence:

$\to T(n) = T(\frac{n}{2}) + T(\frac{n}{2}) + f(|A| + |B|)\\\\ \therefore f(|A| + |B|) = n\\\\ \to T(n) = 2T(\frac{n}{2}) + n$
