Answer:

$2^{85}-1$

Explanation:

Considering the number are stored using binary notations.

If there are total 86 bits and 1 bit is used as sign bit. Then in total one can have $2^{85}$ bit combinations since a bit can be either stored as 0 or as 1.

Therefore, the largest number that can be stored will be $2^{85}-1$ .

To understand it in better way let's scale down the problem to 3 bits representation. The largest number that can be stored using 3 bits is 111 which in decimal form is 7 and is equal to $2^{3}-1$ .

Formulas within table cells always begin with

Montano1993 [528]

The answer is C.

Formulas within table cells always begin with an equal sign.

Here is the sample of some of the formulas :

1. Sum (equation)
=SUM(5, 5) or =SUM(A1, B1) or =SUM(A1:B5)

2. Count ( to count number of cells or rows)
=COUNT(A1:A10)

3. Trim ( Get rid of any space in a cell)
=TRIM(A1)

4. Vlookup ( to look up data from a vertically structured table)
=VLOOKUP(lookup_value, table_array, col_index_num, range_lookup)

5. if statements
=IF(logical_statement, return this if logical statement is true, return this if logical statement is false)

Write a recursive method that finds the number of occurrences of a specified letter in a string using the following method heade

Dafna1 [17]

Answer:

//Java program to find the number of occurrences of a specified character in a string.

// Import the required packages.

import java.io.*;

import java.util.*;

//class declaration

class CharacterCount

{

// Main method.

public static void main (string args[ ] )

{

try

{

// Taking the input from the user.

System. out.print ("Type a string to analyze: ");

// Creating the scanner class object.

scanner input = new scanner (system. in);

String str = input .next();

System.out.print("Type a character to check: ")

String temp = input.next();

char c = temp.charAt(0);

// Calling the method to get the character count.

int count = count(str,c);

// Displaying the result.

system.out.print In("There are " + count + " " + c + " 's. ");

// catching the exception.

catch(Exception e)

System.out.print In("Exception has occured in the class . Program will exit. ");

// Exiting the system.

System.exit(0);

}

// Method to calculate the character count.

public static int count(String str, char a)

{

// checking for null string input.

if(str.equals(""))

{

return 0;

}

else

{

int k = 0;

// Character matching check.

if ( str.substring(0, 1) . equals (Character.toString(a)) )

{

// Incrementing the counter.

k++;

}

// Recursive call

k += count(str.substring(1) , a);

return k;

}

Explanation:

Output should show: Type a string to analyze: welcome

Type a character to check: e

There are 2 e's.
