• This situation is consistent with an overflow error. When the count was incremented beyond the maximum value that can be represented by a fixed number of bits, the count wrapped around to a negative number.

• To ensure that the data gathered from testing a new algorithm is representative of all users, developers should test it on a random sample of users. This will help to avoid bias in the data, as it will be collected from a variety of users with different backgrounds and experiences.

• An undecidable problem is a problem that cannot be solved by a computer program. This is because there is no algorithm that can always provide a correct yes-or-no answer to the problem. Some instances of an undecidable problem may have a solution, but there is no general solution that can be applied to all instances of the problem.

• Step 4 iterates over the list and increments the count variable each time the target value is found. Step 5 prints “true” if the count variable appears more than once in the list.

The code segment assigns the correct number of bonus points to the bonus variable for all possible values of the timer variable. If the timer variable is greater than 60, the bonus variable is assigned 1500 points. If the timer variable is between 30 and 60, inclusive, the bonus variable is assigned 1000 points. If the timer variable is less than 30, the bonus variable is assigned 500 points.
