Ha annyira akarod, legyen egy kicsit komolyabb kerdes:

Ha vki ki tudja bogyozni,hogy miert ezek az ertekek, lecci homalyositson

esetleg egy jo kibogozo algoritmussal is :-)

Some numbers are represented in a form called a variablelength quantity. 
These numbers are represented 7 bits per byte, most significant bits 
first.  All bytes except the last have bit 7 set, and the last byte has 
bit 7 clear.  If the number is between 0 and 127,  it is thus 
represented exactly as one byte.

Here are some examples of numbers represented as variable-length quantities:
         Number (hex)    Representation (hex)
         00000000        00
         00000040        40
         0000007F        7F
         00000080        81 00
         00002000        C0 00
         00003FFF        FF 7F
         00004000        81 80 00
         00100000        C0 80 00
         001FFFFF        FF FF 7F
         00200000        81 80 80 00
         08000000        C0 80 80 00
         0FFFFFFF        FF FF FF 7F

The largest number which is allowed is 0FFFFFFF so that the variable-
length representation must fit in 32 bits in a routine to write
variable-length numbers.
