Interpret LCGFuck™ code-golfinterpreter
Introduction
LCGFuck™ is a Brainfuck-like esoteric programming language invented by me. Inspired by linear congruential generators (LCGs), the idea of using LCGs to program is implemented in LCGFuck™.
An LCG in LCGFuck™ is defined with 5 integers, namely...
@ngn now your code gives warning even if I don't use -Wall
e.g. unused variable ‘d’ [-Wunused-variable] S L f3()_(L r=(L)n<<2*n;I d=1+msk/nt;pthread_barrier_t b;pthread_barrier_init(&b,0,nt);A a[nt];pthread_t t[nt]; ^ ngn.c:6:25: note: in definition of macro ‘_’ #define _(a...){return({a;});} ^ ngn.c: At top level: ngn.c:14:5: warning: ‘min’ defined but not used [-Wunused-function] S I min(I x,I y)_(x<y?x:y)S L gcd(L x,L y)_(W(x,L z=x;x=y%x;y=z)y)S I rev(I x)_(I r=0;F(i,n,r+=(x>>i&1)<<(n-1-i))r)
the ^ are pointing in the wrong place because of copy and paste it seems
in the code that makes a transition from column j-1 to j, we perform a similar set of operations twice - first on x and then on ~x. those could be sped up with simd instructions.
Question
Write a program to accept one string on the console and print back its letters arranged in alphabetical order. The string must only have the following characters:
0123456789abcdefghijklmnopqrstuvwxyz
Rules
The ascending alphabetical order is defined in the given string.
All rep...
Your job is to solve this chess-related game.
The setup of the game is a 7x7 tile grid, you start on a random tile and you have to hop on each tile, until you hopped on all 49 tiles.
Top left corner is (0,0)
Rules:
you can hop on each tile once.
the only move allowed in the game is to hop tw...
@Anush probably not. the fact that compilers prefer non-vectorized code is an indication that simd is likely not worth here. sse instructions process 4 32-bit ints at a time, which should be faster than 4 individual instructions, but we need only 2 at a time and it may be slower in our case.
