1. Complete the code for a, b, c in ML (SML). And answer part d of question 1

a) Write a function bxor of type bool list -> bool that takes a list of Boolean values and returns the logical or exclusive OR of all them. (it should return true if the number of true values in the list is odd and return false if the number of true values is even.) If the list is empty, your function should return false.

b) Write a function member of type a * list -> bool so that member (e, L) is true if and only if e is an element of list L.

c) Write a function evens of type int list -> int list that takes a list of integers and returns a list of all even elements from the original.

d) Name Two Examples from C++ where a variable is live (in use) but not in scope (i.e. not visible at the moment).
