The Bean Counters

Beans are a cheap commodity, so to count them is a rather silly thing to do. A "bean counter" is one who nitpicks over small things in order to save costs.

Sorting Algorithms

The 10 algorithms tested are:

bubble sort

template<typename T>
inline void bubbleSort(T * array, int size) {
	for (int i = 0; i < size; i++) 	{
		for (int j = 0; j < size - 1; j++) {
			if (array[j] > array[j + 1]) {
				T swap = array[j + 1];
				array[j + 1] = array[j];
				array[j] = swap;
			}
		}
	}
}

selection sort

template<typename T>
inline void selectionSort(T * array, int size) {
	for (int i = 0; i < size; i++) {
		int min = i;
		for (int j = i; j < size; j++) {
			if (array[min] > array[j])
				min = j;
		}
		T temp = array[i];
		array[i] = array[min];
		array[min] = temp;
	}
}

insertion sort

template<typename T>
inline void insertionSort(T * array, int size) {
	T curr;
	int j;
	for (int i = 0; i < size; i++) {
		curr = array[i];
		for (j = i; j > 0 && array[j - 1] > curr; j--) {
			array[j] = array[j - 1];
 		}
		array[j] = curr;
	}
}

merge sort

template<typename T>
inline void mergeSort(T * array, int size) {
	T * temp = new T[size];
	mergeSort(array, temp, 0, size - 1);
	delete[] temp;
}

template<typename T>
inline void mergeSort(T * array, T * temp, int start, int end) {
	if (start < end) {
		int mid = (start + end) / 2;
		mergeSort(array, temp, start, mid);
		mergeSort(array, temp, mid + 1, end);
		merge(array, temp, start, mid + 1, end);
	}
}

template<typename T>
inline void merge(T * array, T * temp, int startA, int startB, int endB) {
	int aptr = startA;
	int bptr = startB;
	int idx = startA;
	while (aptr < startB && bptr < endB + 1) {
		if (array[aptr] < array[bptr]) {
			temp[idx] = array[aptr];
			idx++;
			aptr++;
		}
		else {
			temp[idx++] = array[bptr];
			bptr++;
		}
	}
	while (aptr<startB) {
		temp[idx] = array[aptr];
		idx++;
		aptr++;
	}
	while (bptr < endB + 1) {
		temp[idx++] = array[bptr];
		bptr++;
	}

	for (int i = startA; i <= endB; i++) {
		array[i] = temp[i];
	}
}
