merge 2-d arrays(store them as 1-d vector, because it's easy to serialize)
#include <iostream>
#include <vector>
using namespace std;
#define IndexType int
void merge_local_vectors(vector<IndexType> &first, vector<IndexType> &second, int pair_size1, int pair_size2, int key1, int key2) {
int ssz1 = first.size(), ssz2 = second.size();
int i = 0, j = 0;
