【单选题】
关于排序的选择法和冒泡法，下列说法不正确的是_____。
A.
“选择法”和“冒泡法”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”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.
对于n个元素来说，选择法和冒泡法排序都需要经过n-1次排序过程，每次排序时采用的排序策略不同
