Here's a breakdown:
* The "problem" is resolved: The core conflict of the play is the clashing personalities of Felix Unger, the neat and neurotic character, and Oscar Madison, the messy and carefree one. Throughout the play, their attempts to live together lead to constant arguments and frustration. In the end, they acknowledge that their differences are too much to handle, and Oscar decides to move out.
* A possibility of reconciliation: While they are initially angry and frustrated, there is a sense of reconciliation as they realize their dependence on each other. Oscar even says, "Maybe I'll come back, maybe I won't. You never know," leaving the door open for a future reunion.
* Hope for change: The ending suggests that both Felix and Oscar are open to changing their behaviors, acknowledging that their individual habits are problematic. This implies that they might be able to function better as roommates if they learn to compromise and adapt.
Overall, the ending of "The Odd Couple" leaves the audience with a sense of hope and possibility for the two characters. While their relationship may be strained, there's a chance for reconciliation and growth, hinting at the possibility of a future where they can find a balance and live together in a more harmonious way.
