Give the domain and the range of the following functions: a) The function that maps non-negative integers to their last digit. b) The function that maps a positive integer n to the largest positive integer k such that k^2 <= n (k^2 is k squared). c) The function that maps a bit string to the number of one bits in the string. d) The function that maps a bit string to a truth value indicating that the number of zeros in the string is even.

Domain = set of values that can be fed into the function. Range = set of values that can actually be returned by the function.
