【单选题】下列三种算法是经常应用的内排序算法:插入排序、选择排序和冒泡排序。阅读下列算法,回答问题。 INSERTION-SORT(A) 1. for i=2 to N 2. { key = A[i] ; 3. j =i-1; 4. While (j>0 and A[j]>key) do 5. { A[j+1]=A[j]; 6. j=j-1; } ...
A.
“选择法”和“冒泡法”都是每一轮次找出一个最小值元素,只是寻找最小值元素的方法不一样,在效率方面没有什么差别;
B.
“选择法”通过将所有未排序元素与当前轮次待寻找的最小值元素进行比较,获得当前轮次的最小值元素;而“冒泡法”通过相邻元素的两两比较,一个轮次完成也能获得一个最小值元素;
C.
虽然“选择法”和“冒泡法”都是每一轮次找出一个最小值元素,但选择法每轮次仅比较,没有交换,直至找到最小值后做一次交换;而冒泡法每一轮次是通过相邻元素比较来找最小值,如果不满足排序,则交换相邻两个元素,交换可能频繁发生。这样来看,选择法比冒泡法要快一些;
D.
上述说法有不正确的。
