Table 1 shows a list of expressions and assignments to the variables in the expressions. State for each, whether or not the expression is an invariant of the assignment. Justify your answer, either by using the invariant rule for assignment statements, or by giving a counter example. (3% per assignment) Assignment Expression m. n = m + 10,n + 2 10m - 2n m, n = m + 2, n + 10 10m - 2n k,s=k+25, s + 75 3ks mn m, ne km-n) kk n = 2n even(n) Table 1: Fill in entries marked out Invariant ? ? ? ? ? Note that the expression even(n) is true when the argument n is even and false when n is odd
