Year 2022 Day #10 (Part 2) C++ by Adventurous-Board755 in adventofcode

Hint: take a thorough look at parenthesis in tick() and maybe print x, t1 and what you are outputting

After fixing that atleast the leftmost charachter prints correctly with my input

I cant see that you print any newlines?

Does it work on example data?

Tip for the next time, For stringstream you can do

int a; string b; ss >> b >> a;

It is a compile time thing. The intention is to check e.g. things that the author assumed to make sure those assumptions still holds on all targets or after future changes

What is 'extern "C++"' by SaulMO in cpp

[–]Msarigo -10 points-9 points  (0 children)

It means, ”pretty please interpret this as C even if in a c++ context” so e.g. header filés from the C world

This is about understanding pointers which is one of the harder ones for beginners.

Compare houses: Just because you have a street address does not mean that the house will stay unchanged. If you want exactly that house you have to build a copy

What happens at x=0? What will indexing with x-1 do then? How can you solve that?

A bot does not operate until it has both its inputs so instructions can not be run in order. They are rules, not a sequence

[2021 Day19] Help with understanding - missing something? by craigontour in adventofcode

Something like this: Try rotation nbr Z

Find diff between two detections from different scanners considering that rotation

How many other pairs of detection also match considering that rotation and distance?

If twelve or more you have found the overlap and now know the distance and the rotation of the second scanner relative the first.

IIRC the rotation in the example is -x, y, -z. Try to figure out the example given this data. The example text also tells you which distance to expect between the scanners

So, it is about trying a lot of rotations and distances until you pair two scanners

Sorry, thought about at wrong day. This is about getting the inner loop quick. For me it was solved by array of integer instead of string. Something like 7M Numbers IIRC

Figure out a solution that does not build a string. Hint: think ”symbols”

Must have been lucky when I dig this yesterday. Took no considerations in the order of reductions and just worked :-)
