(a) a = 2 * (b - 1) - 1 {a > 0} (b) b = (c + 10) / 3 {b > 6} (c) a = a + 2 * b - 1 {a > 1} (d) x = 2 * y + x - 1 {x > 11} (e) a = 2 * b + 1; b = a - 3 {b < 0} (f) a = 3 * (2 * b + a); b = 2 * a - 1 {b > 5} (g) if (a == b) b = 2 * a + 1 else b = 2 * a; {b > 1}

2. Construct DAG for the expression a + a * (b - c) + (b - c) * d. 3. Generate the target code for the following expression using two registers R0 and R1. w = (a - b) + (a - c) * (a - c)
