there are different ways of representing numbers:
1
I
one
0x01
00000001
but it doesn't mean we have dozens of number one! we only have 1 value that we use different encodings for it to represent it (numeral, roaman, text, hex, binary). what you did here was only to change the encoding.
and what you did here is just playing with modular arithmetic.
neither one of these have anything to do with this topic: collision.
