libcommunism

A satirical C library that redistributes array wealth according to Party doctrine. Mocks communism, Stalinism, and left-authoritarian ideologies through code.

The Formula

Let S = Σ aᵢ. The redistributed array A' is defined as:

a'[0]      = S − (k − 1)   // The Party Secretary — takes everything
a'[1..k-1] = 1             // The Apparatchiks — minimum ration
a'[k..n-1] = 0             // The People — liquidated

Where k is the size of the ruling class (Party + apparatchiks).

Example

Input: [3, 5, 1, 2, 9, 7, 5, 4], S = 36, k = 4

Output: [33, 1, 1, 1, 0, 0, 0, 0]

• a'[0] = 36 − 3 = 33 — the Party Secretary's share
• a'[1..3] = 1 — rations for the privileged
• a'[4..7] = 0 — everyone else

API

#include <communism.h>

// Redistribute an int64_t array in-place.
// Returns COMMUNISM_OK, COMMUNISM_ERR_ARGS, or COMMUNISM_ERR_BURZH.
int communism_apply(int64_t *arr, size_t n, size_t k);

// Same for double arrays.
int communism_apply_f(double *arr, size_t n, size_t k);

// Sum helpers.
int64_t communism_sum(const int64_t *arr, size_t n);
double  communism_sum_f(const double *arr, size_t n);

// Human-readable accusation for a return code.
const char *communism_strerror(int rc);

Return Codes

Code	Value	Meaning
COMMUNISM_OK	0	Success
COMMUNISM_ERR_ARGS	-1	Invalid arguments (NULL, k=0, k>n)
COMMUNISM_ERR_BURZH	-2	Petty-bourgeois deviation: leader's share would be less than 1

Petty-Bourgeois Deviation

If the resulting leader share S − (k−1) < 1, the library refuses to proceed and returns COMMUNISM_ERR_BURZH. The array is left unmodified.

double arr[] = {0.5, 0.5};
int rc = communism_apply_f(arr, 2, 2);
// rc == COMMUNISM_ERR_BURZH
printf("%s\n", communism_strerror(rc));
// PETTY-BOURGEOIS DEVIATION: you attempted to give the leader less
// than a rank-and-file Party member. You are under arrest.
