Quick Sort Algorithm review-bubble sort bubble sort and quick sort (python implementation)

The process of bubbling sorting is to first compare the keywords of the first record with the keywords of the second record, and, in reverse order, Exchange two records and then compare the keywords for the second record and the third record. And so on, until the n-1 record and the nth record's keywords have been compared. The above process is called the first bubbling sort, then the second trip to the previous n-1 the same operation, ...The quick

Bubble sort of thinking python bubble sort

The time complexity of bubble sorting is the idea of O (n^2) bubble sort: compare two adjacent elements each time, and swap them if they're in the wrong order.For example, there are five numbers: 12, 35, 99, 18, 76, from the big to the small sort, compare the adjacent two bits First trip: First time compar

Python and Bubble sort

to the last one, we call this a trip, there are several comparisons in this trip.Since a trip is only classified as one number, if there are n digits, a n-1 trip is required.Because the number after the return does not have to compare again, so each trip only need to compare n-1-i times (I is the number of executed trips).The key step that can be derived from the bubbling sort is two loops:1 for(i =0; I 1; i++){2 for(j =0; J 1-I.; J + +)3 if(
