# Mixed Up Code PracticeΒΆ

Try to solve each of the following. Click the Check Me button to check each solution. You will be told if your solution is too short, has a block in the wrong order, or you are using the wrong block. Some of the problems have an extra block or two that aren’t needed in the correct solution. Try to solve these on your phone or other mobile device!

        5-14-1: The following program segment should print if your guess is too low, correct, or too high  But, the blocks have been mixed up.  Drag the blocks from the left and put them in the correct order on the right.  Click the Check Me button to check your solution.int guess = 10;

---
System.out.println("You are right!");

else
---
System.out.println("Your guess is too high");
        5-14-2: The following program segment should print either "You can go out" if you don't have any homework and have cleaned and otherwise should print "You can not go out". But the blocks have been mixed up and includes one extra block that is not needed in a correct solution.  Drag the needed blocks from the left and put them in the correct order on the right.
