For each block of code, fill in the intermediate conditions, then use them to state whether the precondition is sufficient to guarantee the postcondition. If the precondition is insufficient, explain why and indicate where the conditions don't match up 1.{x > 0} z = x - 1 {_____________} w = 2*z; {_________} w = w + 1; {w > 1} {y greaterthanequalto w} x = w + 2; {___________} y = y + 2; {___________} z = y {z greaterthanequalto x}
