what are some strengths and weaknesses of GIF?
Pros: Great for images with limited number of colours (like drawings), The only widely-supported animated image format Cons: On most photographs, loses image data in a noticeable way (lossy), Lingering patent discomfor

pros and cons of PNG?
Pros: • Often better compression than GIF ▫ Though sometimes worse • Good support for transparency • Makes combining images easier • Lossless!! cons: • Various animation proposals, but none standard and supported by a lot of browsers • Achieves good, but not great compression ratio on photograph
300
when are tries efficient?
when there is dense branching in autofill in text and search engines

How do you mirror an image horizontally? vertically? decrease size? pixelate?
Store the pixels in inverse order in each row Store the rows in inverse order Store only even numbered row group 4X4 and find the average colour

What is going on here? name = prompt("What is your name?"); yearOfBirth = prompt("What year were you born in?"); ageTurning = 2013 - yearOfBirth; document.write("Hello, "); document.write(name); document.write("!
You will be turning "); document.write(ageTurning); document.write(" this year, if you haven’t already.");
text box: what is your name? text box: what year were you born in? perform calculation 2013-yearOfBirth write: Hello, eg Gordon! You will be turning 20 this year if you haven't already.

pros and cons of JPEG?
pros:• Awesome image compression for photographs • Virtually no noticeable loss of image quality on photographs cons:• Compression artefacts on other image types • Should not be used as primary format when doing image manipulation
400
how are heaps organized?
the first node possesses the highest value and then each node has children with a lower value
500
how do we find how many bytes are in a TUF file?
4+3XwXh=bytes in the file

express this algorithm in words: number=Math.floor(Math.random()*9 + 1); guess=prompt("I have a number from 1 to 9. Guess it."); numGuessesLeft=6; while ((numGuessesLeft > 0) && (guess != number)) { if (guess"); } else { document.write("Wrong! All your guesses are used up.
"); } document.write("The number was: " + number); 44
1. Pick a random number between 1 and 9 2. Ask user to guess it 3. Set number of guesses left to 6 4. Repeat as long as user has not guessed number yet, and number of guesses left is greater than 0: 1. If last guess was too high, tell user it is too high and give them another guess 2. Otherwise, tell user it is too low and give them another guess 5. Tell the user whether they’ve guessed correctly 6. Tell the user the number

what are stack effective for?
games with backtracking applications that need others to run
