Doesn't really matter.
The only people who actually care are the nerds who want to pick the OP image.
Is there really anyone else that has reasons to complain?

because it's a waste of a bit of a thread and it puts another in the archive, plus it leads to thread wars

How are you enjoying this year's advent of code?
Here's my day 3 pt 2.
int valid_triangle(int *arr)
{
if (arr[0] + arr[1] > arr[2] &&
arr[0] + arr[2] > arr[1] &&
arr[1] + arr[2] > arr[0])
return 1;
else
return 0;
}

int main(void)
{
char *ins = get_filebuffer(DAY(03));
int sides[3][3] = { { 0 } };
unsigned col = 0, row = 0;
unsigned valid = 0;
char *tok = strtok(ins, " \n");
while (tok != NULL)
{
sscanf(tok, "%d", &sides[row++ % 3][col % 3]); /* vertical */
if ((row % 3) == 2)
col++;
if (!(row % 3) && !(col % 3))
{
unsigned i; /* flatten array */
for (i = 0; i < 3; i++)
{
int arr[3] = { sides[i][0], sides[i][1], sides[i][2] };
if (valid_triangle(arr))
valid++;
}
}
tok = strtok(NULL, " \n");
}
printf("Valid triangles: %d\n", valid);
free(ins);
return 0;
}
