Consider the Java code below. We have already fleshed out a loop invariant for you. Your task is to fill in the missing Hoare logic justifications so that we have a proof that mult returns the product of x and y. You may be inspired by worked examples from class. // precondition: x >= 0 && y >= 0; int mult(int x, int y) { int kx, n = while (k = 0) if (k%2 k /= 2; == y, res = 0; { // @loop_invariant x 1) res = res + n;B * y knres; n = 2; } return res%;B } // post-condition: returns x y *
