You must be shitting me. I used OS X preview to filter colors in the picture and look for patterns. What I didn't know was that this automatically saved the changes to the picture. When I later was on the right track the answer was gone from the file. I later spent a whole day afterwards printing ou...

lol. had same problem. i guessed it was something like that. pretty confusing.

some for loops and if statements loosely narrowed down the possibilities, though a lot. first I made the program to print out all the different possibilities. pain in the ass I noticed: - first of all because the possibilities, though narrowed, were still many and for the computer to print out takes...

lol...envy you phyton programmers. Im not gonna post my messy c++ code here.
I had to find a way to calculate the value part by part and store the answere in smaller bits in a vector.
must make a c++ class based on this problem, so I never have to mess with large number coding ever again.

c++ solved it for me: int chartoint(char ch) { ch = ch - 48; return int(ch); } int main() { char buff1 = '0'; char buff2 = '0'; char ch; int ans; cin.get(ch); while (ch != '\n') { if (isdigit(ch)) { ans += chartoint(ch); } else if (ch == 'x') { ans += chartoint(buff1) + chartoint(buff2); cin.get(ch)...

Nice solvings. c programmer as I am, I too did convert the code to c. however, I found it cleanest to just copy the function calc() and not make a class to call from: int calc(int depth) { if (depth == 0) return 1; int cc = calc(depth - 1); return ( cc + (depth % 7) + ((((cc ^ depth) % 4) == 0) ? 1 ...
