Accept the failure and as kitschy as it might sound, embrace it. There's nothing wrong with failing.
Once you do that try to understand what caused it, try to find other's solutions to similar technical questions. See if and how different your answer was. Also, not all failures are because of a wrong answer, it's sometime the process that lead you to it that failed you.
As an interviewer I always advice candidates to approach me whether by email or phone and ask why they failed. I understand, It is sometimes hard to accept the reasons and you might not always agree with the interviewer but if you really want to grow because of the experience you must be know why you failed.
Greater people already said it, best way to learn is to fail.
Whatever you do, never ever give up!
Hope this helps.
