Which random sequence would you associate the below snippet with?

for (var i:int = 0; i<4; i++){
  trace(int(Math.random()*2) - 1 | 1);
}

Which of the below sequences would you associate with the following snippet?

for (var i:int = 0; i<10; i++){
  trace(i & 2);
}

You may want to work this out on paper

A quadratic Bézier curve is the path traced by the function B(t), given points P₀, P₁ and P₂.

The above is from wikipedia.

Which of the below lines of actionscript accurately represents the B(t) function? Hint: Try working it out yourself and then choosing the answer that is closest to your own. You can use this template over at wonderfl to help you work it out:

What is the length of the following ByteArray?

var bytes:ByteArray = new ByteArray();
bytes.writeInt(0xFFFFFF);

What is the length of the following ByteArray?

var bytes:ByteArray = new ByteArray();
bytes.writeInt(0xFFFFFF);
bytes.writeUnsignedInt(0xFFFFFF);

How many bytes does it take to represent a short in a ByteArray?

What will the following snippet trace to the output window?

var bytes:ByteArray = new ByteArray();
bytes[0] = 0;
bytes[1] = 0;
bytes[2] = 1;
bytes[3] = 1;

bytes.position = 0

trace(bytes.readInt());
