I copied the input to start from location 54 in memory so that I could use 0-53 for my own purposes.
After the copy, I stored my jump values (and some other values) in the single-digit memory locations so that jumping would be super easy. If a jump value needed to change, no problem, just change the hard-coded value that gets stored in memory during init.
I also stored the subroutine locations of each input handler in the location corresponding to that inputs ordinal value to make input handling really easy. My input iterator was stored in memory 0, so in order to handle the next input, all I had do was 0<<<c (unless it was a digit).
My solution (250 characters):
Code: Select all

I am using excell for the HVM codding:
It concatenates the code and computes the addresses, otherwise I am codding manually.
... I am describing stack states at starts and ends of code lines.
I will remove the sum of code here... of course the formulas are hidden ...
I have problems to format it properly here.. Tabs don't align
.

Hi hackers, what about your cycle counts? Let's compare
8+5*(1+2)
798 cycles
(((26+10)*(28*25*12))*((5+9)+(20+23))+24-12-23*20)
3098 cycles
2342524*(234663+123551+512123)*41241412-23415354
2727 cycles

integer overflow ... have you used HVM from the pages?
output 1412163254, 2674 cycles (with simulator mentioned in next post)
... seems my solution when digit serves as an operation *10+digit when no other operation is found favours you in long numbers ...
try
1234567897 as an input
output 1234567897, 583 cycles (*)

Nice simulator ... (at least input preparation is really easy). It's a pitty I have only the last rat as a HVM challenge.
BTW: Is there an option to change the font size in the code window? I have problems to read the code here.
