When Karel picks up a beeper, what happens to the beeper?

When Karel picks up a beeper, the beeper is indeed stored in Karel's bag. This means that Karel retains the beeper for future use, allowing for actions such as placing it back down later or using it in other commands. The concept of Karel having a "bag" helps to visualize how Karel can transport items within the grid environment, which is essential for programming tasks that involve managing resources. By consistently allowing Karel to pick up and store beepers, programming becomes a more versatile and interactive experience, enabling more complex behaviors and objectives as Karel navigates the grid.
