JOIN and INNER JOIN are redundant. You really just need an array like
this:
{"INNER JOIN", "LEFT JOIN", "RIGHT JOIN"}
And once you have that, you'll notice that you always use the word
join, and so you can change your code to always supply that part and
only look for the first part in an array like this:
{"INNER", "LEFT", "RIGHT"}
At this point, your index lookup becomes much simpler.

what's the most efficient way to shuffle huge bitvectors using GCC 
you could try rolling your own loop 
int ch1, ch2;
while ((ch1 = fgetc(fp1)) != EOF && (ch2 = fgetc(fp2)) != EOF)
{
int i, dst = 0;
// assuming msb goes first
for (i=7; i>=0; i) {
dst = (ch1 & (1<<i)) << (2*i + 1);
dst = (ch2 & (1<<i)) << (2*i + 0);
}
putc(dst >> 8);
putc(dst & 0xFF);
}
You can ma

Uniformly shuffle 5 gigabytes of numpy data 
The following assumes your data is already divided into
easilyretrievable records of some sort. (I don't know if there's a
standard file format for numpy data.)
Create an index of the data in the form of a dict, mapping each unique
record ID (0 through n  1) to some means of finding the data again.
For instance, if it's all in one binary file, you'd store a tuple of
the form (file_offset, re

How to create a looping shuffle method in an array 
The shuffle method will look like this :
private void shuffle() {
Deck ob = new Deck();
int x = deck.size()  1;
for(int i = 0; i < TIMES_TO_SHUFFLE + 1; i ++){
int r1 = (int) Math.floor(Math.random() * x);
int r2 = (int) Math.floor(Math.random() * x);
ob.swap(r1, r2);
}
}

Algorithm of array shuffle with distance restriction 
Here's some pseudo code that may help. Note that the algorithm is
focused on conforming to the distance rule, sacrificing uniformity* in
the process.
choose a random array index (call it "i" )
there's number at array[i] (call it "A")
set "count" to 0
for each "j" such that array[j] is a valid location for "A"
{
there's a number at array[j] (call it "B")
if ( "B" can be legally moved to
