Do you understand the concept of bit shifting?
ie
000110 shifted left gives
001100
and
000110 shifted right gives
11
In other words the bit pattern moves left or
right and
Danny and Dave,
super thanks on the plain text advice. i'm sending this mail on plain
text, please let me know if it turned out to be otherwise
back to the problem
just googled binary and i now have some idea on it. i now understand
turning on 16 and 8 gives 24 and thus 4+8 = 12. why is this? i no

Whatever mail program you're using is apparently defaulting to
html. Find a menu item that specifies 'text' or 'plain text' or
'text only'.
Or tell us what email program you're using, w
Thanks joel
Could you elaborate more on bitwise, and why do we need to double bit. I
experimented with some input
ShiftAnd('pattern', 'textcontainingpatternandpatern')
print out the (masks, accept_state), looks like bellow, the rest make sense
couse the numbers are doubled, but the 't' goes 4+8
You both posted in html, rather than text mode.

Only the first time through the loop, when bit == 1

hey guys,
i am trying to understand this code pasted bellow,
1. what is line means? mask[c] |= bit
2. then the line bit *=2, this increment the bit to 2 for each character?
3. what is this line means? accept_state = bit //2
4. lastly, what is this scary line means? D = (( D << 1) + 1) & masks [ c
