排序算法(9)--Distribution Sorting--分布排序[1]--Counting sort--计数器排序 1.基本思想 假设数序列中小于元素a的个数为n,则直接把a放到第n+1个位置上。当存在几个相同的元素时要做适当的调整,因为不能把所有的元素放到同一个位置上。计数排序假设输入的元素都是0到k之间的整数。 2.实现原理 为一组数在排序之前先统计这

Distribution counting--- unusual approach to sorting 计数排序(Counting sort): requires: Key values to be within a certain range, lower to upper. 要排序的值在一定范围内。 通过记录所有数中,比该数小的有几个,来安排其位置。可以用辅助数组(auxiliary array)记录范围内比该值小(大)的有几个,也可以用...
However, Counting Sort is not a comparison-based sort and requires a range of input data to be known beforehand. What is Radix Sort and How Does it Work? Radix Sort is a non-comparative sorting algorithm that sorts numbers digit by digit, starting from the least significant digit to the ...
Counting sort [Best/Avg/Worst: O(N)] Assuming the data are integers, in a range of 0-k. Create an array of size K to keep track of how many items appear (3 items with value 0, 4 items with value 1, etc). Given this count, you can tell the position of an item — all the...

2) distribution based sorting algorithms. Counting Sort - A simple and fast sorting algorithm that creates an integer array of size |S| and using the ith bin to count the occurrences of the ith member of S in the input. Each input is then counted by incrementing the value of its corresp...
The present invention is not limited to an MSD listed radix sort as set forth in the preferred embodiment of the invention, but may be advantageously applied to essentially any type of bin sort such as an LSD listed radix sort, or distribution counting sort (MSD and LSD). The present inven...
