Fastest search code in the world!! :) (not related to webbing but?)

This is implementation of the radix sort in binary base with C++ code. You could see the O(1) implementation of radix sort with huge fast difference from other algorithms.

void radixAt(int numberOfItems,int byteNumber, int *temp, int *arr){
int count[256];
int index[256];
for(int i = 0; i<256; i++){//fill all elements of count array with 0
count[i] =0;
for(int i = 0; i < numberOfItems; i++){//determine the number of each byte amounth
count[(arr[i] >> (byteNumber*8))&0xff]++;//take byte to controll
index[0] = 0;
for(int i = 1; i < 256 ; i++){//for each byte amounth, keep the index space
index[i] = index[i-1] + count[i-1];
for(int i = 0; i < numberOfItems ; i++){//fill elements according to their byte to temp array for next call to main array
temp[index[(arr[i]>>(byteNumber*8))&0xff]++] = arr[i];
void radixSort (int *arr, int *tempArr, int size){
radixAt(size, 0, tempArr, arr);
radixAt(size, 1, arr, tempArr);
radixAt(size, 3, tempArr, arr);
radixAt(size, 4, arr, tempArr);
