lubasha [3.4K]

Answer:

speed up of process creation increases in the effective access time of memory

Explanation:

Virtual memories are often used in order to save up ram for other applications and not being limited by the actual physical memory that we have, in this case the virtual memory is slower than normal memories since they are not actual memories and are restricted to the spee of the connection or the speed of the disk where they are located.

Write a function string middle(string str) that returns a string containing the middle character in str if the length of str is

Katen [24]

Answer:

function getMiddle(s) {

return s.length % 2 ? s.substr(s.length / 2, 1) : s.substr((s.length / 2) - 1, 2);

}

// I/O stuff

document.getElementById("submit").addEventListener("click", function() {

input = document.getElementById("input").value;

document.getElementById("output").innerHTML = getMiddle(input);

});

Explanation:

// >>> is an unsigned right shift bitwise operator. It's equivalent to division by 2, with truncation, as long as the length of the string does not exceed the size of an integer in Javascript.

// About the ~ operator, let's rather start with the expression n & 1. This will tell you whether an integer n is odd (it's similar to a logical and, but comparing all of the bits of two numbers). The expression returns 1 if an integer is odd. It returns 0 if an integer is even.

// If n & 1 is even, the expression returns 0.

// If n & 1 is odd, the expression returns 1.

// ~n & 1 inverts those two results, providing 0 if the length of the string is odd, and 1 if the length of the sting is even. The ~ operator inverts all of the bits in an integer, so 0 would become -1, 1 would become -2, and so on (the leading bit is always the sign).

// Then you add one, and you get 0+1 (1) characters if the length of the string is odd, or 1+1 (2) characters if the length of the string is even.

Suppose you are given three data items that indicate a starting index in a list, an array of characters, and an array of link in

Artemon [7]

Answer:

see explaination

Explanation:

INCLUDE Irvine32.inc

;declare the variables

SPACE = 32

startIndex = 1

.data

statement BYTE "The correct sequence of array: ",0

; declare the chars('H','A','C','E','B','D','F','G')

chars BYTE 48h,41h,43h,45h,42h,44h,46h,47h

sizeOfArray = ($ - chars)

links DWORD 0,4,5,6,2,3,7,0

outputArray BYTE sizeOfArray DUP(?)

.code

main PROC

; assign starting index

mov eax,startIndex

; assign offset of array chars

mov ebx,OFFSET chars

; assign the size of the array

mov ecx, sizeOfArray

; assign the offset of array links

mov edi,OFFSET links

; assign the offset of new array

mov esi,OFFSET outputArray

; call the traverseLink procedure

call traverseLink

; display the characters of new array

mov edx,OFFSET statement

call writeString

; assign the offset of new array

mov esi,OFFSET outputArray

; assign the size of the array

mov ecx, sizeOfArray

; call the procedure printArray to print the ordered array

call printArray

exit

main ENDP

traverseLink PROC

forLoop:

; get the character at index eax

mov dl,[ebx+eax]

; assign it to new array

mov [esi] , dl

; get the value at the next index

mov eax,[edi+eax*4]

; goto next location of new array

inc esi

; repeat until ecx=0

loop forLoop

ret

traverseLink ENDP

printArray PROC

forLoop:

; get the character at index eax

mov al,[esi]

; print the character

call WriteChar

; increament esi to get next character

inc esi

; print the space character

mov al,SPACE

call WriteChar

loop forLoop

call Crlf

ret

printArray ENDP

END main

Megan has written the following rough draft for her assignment. Choose the correct way to complete each sentence. Sarah is creat

atroni [7]

Answer:

I. hatching

II. filter

Explanation:

Sarah is creating an image. She wants to achieve tonal effects with parallel lines by varying their densities and distribution patterns. She will use hatching to do this. She also wants to add special effects on the image. Therefore, she will use filters.

Hatching refers to an art technique in which parallel lines are used to shade by drawing them closely together.

Stippling is an art technique used in the making of patterns by using small dots.

Filters is a technique of changing image characteristics. It is used to change the picture characteristics & to add special effects to an image such as the shade, contrast, tone, brightness etc.

We therefore see that, hatching and filter are the correct answers respectively
