Sequences Quiz

1. Simplify the following expressions, assuming that x and y are sequences, i, j and k are integers and that all indices and parameters are in bounds:

1. seq of int{i, j, k}[1]
2. x.drop(i).take(j) [Hint: use the slice member function]
3. x.take(i)[j]
4. x.drop(i)[j]
5. x.drop(i).head
6. x.take(i).last
7. (i..j)[k]
8. (x ++ y)[i] [Hint: use a conditional expression]
