not me, idek what each of the sort does

Insertion Sort

• Used when a large part of the data is already sorted
• During each pass the last element from the unsorted part is inserted into the appropriate place in the sorted part of the array
• A linear search is conducted to find the correct place to insert
• As each sorted element is checked it is moved to the left/right to make room for the new elements
• At each pass the sorted section of the array increases by 1
• Process continues until the unsorted section = 0

Selection Sort

• During each pass a linear search is performed
• A marker is placed at the first cell in the array and then search through the array from that position onwards looking for the smallest value
• When the smallest value is found, it is swapped with the marker’s cell value. This naturally places the smallest value at the front of the array
• The next step is to increment the marker to the next cell and repeat the process. When the marker reaches the last cell, the array is sorted.
• procedure selection sort

swap procedure would include temp value

Bubble Sort

• popular amongst novice programmers
• main logical structure is based on traversing an array and switching adjacent pairs of values that are not in the correct order
• after one travers the largest value will have ‘bubbled’ to the end of the array. This is repeated until all values are in the correct cells

BEGIN bubbleSort with numbers
Set index to first index of numbers +1

WHILE index <= last index of numbers

IF numbers[index –1] > numbers[index] THEN

Swap(numbers[index –1] and numbers[index])
ENDIF

Increment index

ENDWHILE

END

brooo thank you so much

Nw bro I'm so confused with the sorts too

What is a double

a larger version of a float, so like if u express Pi for example it would probably be a Double.

 

[igor9]

also i just woke up and still have 30 pages to read, lord have mercy

 

[Alyosha]

The exam is in 4 hours and i don't know 1/3 of the content

 

[igor9]

let's lock in then, i'm not gonna check this forum again until after the exam to lock in, so I wish u all luck

 

[keyboardsmash]

i wish you all good luck in the software exam. i need to lock in for the next 2-3 hours and hope the knowledge about my optional topic is stuck in my head. band 5 please oh please

When it asks for like TWO examples is there any downside to giving 3?

no just wasting your own time, which you could've used to improve some of your other responses. NESA says that they don't mark people down for going over as they said that "The students who go over the expected writing time and length, penalise themselves by reducing their time for other sections".

it honestly depends though. like you mightve actually written 2 valid examples out of 3, therefore still achieving full marks for that question.

how did everyone find it?

not bad, what was the final expression for boolean u guys got, last q?
(option topic 2)

 

[keyboardsmash]

the exam wasn't actually that bad as i thought it would be. sadly could not do much of section 3 of interrelationship between hardware and software, and i guarantee you my algorithms were not valid (but i can still get marks for attempting, I'd say i did some good attempts) but tried my best. hoping for 70-80?

i never ended up finishing that one, only got a truth table down. :/

i dont remember exaclty but i had 2 not gates and 3 other gates

Option 2 was weird like less syllabus content than usual, with unusual questions

what was unusual?

 

[Demons]

would you reckon the test was easy? or like moderate difficulty, some questions were worded weird but they weren't hard to understand.

I really hope aligning this year is alright, so maybe a lower cut off around 85 for b6, if the test was worded wack? idk though I found the test alright.

lil bit easier than the past papers imo
