The following Haekll expression defines the list of integers from 0 to 1000:

list = [ x ] x

Make simple modification to this expression to define

(a) The list oddlist of all odd numbers between 0 and 1000. Do not use the predefined Haskell function odd.

(b) The list sqlist of all positive integers n such that n 50000. Do not use floating-point numbers (Hint: you have to replace the "trivial" Boolean condition True by a suitable expression of type Bool.)
