need help identify a classical pieces

[sam1741]

hi all,
Greetings.

I have heard this classical pieces as background music on some of tv shows
really wish I know what pieces and who is the composer (i think might be Mozart)
This is a fast, lively piece, played in piano,
have some fast major scale inside.

Because I dono the key, i write out in numbers,  (i use the 'dot' in front and behind to identify it as different octave)
hope someone could help me identify it.
The middle of the song is like this.


(some scale) 123456543212345654321 (some part I forgot)
4 - .7 - 1 |  1. 1. 1. 1. 1. 7 6 5# -  | 5# 5 5 5 5 6 7 1.- | 1. 1. 1. 1. 1. 1. 7 6 5# |
5# 5 5 5 5 6 7 1 - |  1. 3. 3. -  | 7 4. 4. - | 5# 3. 3. - | 4 2. 2. - |

Something like this

Sorry I forgot most of the part
hope someone could help me identify the tune


Thanks in advance
