无法似乎弄清楚我写了什么排序算法

Question

We recently stared doing sorting algorithms in school. So I wrote the code below, it works but I don't know whether it is Bubble sort or Selection Sort.

for i in range(0 , len(array)):
  for j in range(0 , len(array) -1):
    if (array[j] > array[j +1]):
      array[j] , array[j + 1] = array[j + 1] , array[j]

Answer 1

Algorithm: Bubble Sort

Because it repeatedly swaps the adjacent elements if they are in the wrong order.

for i in range(0 , len(array)):
    for j in range(0 , len(array) - i -1):
        # traverse the array from 0 to len(array) - i - 1
        # Swap if the element found is greater 
        # than the next element
          if (array[j] > array[j +1]):
              array[j] , array[j + 1] = array[j + 1] , array[j]

There is an error in your second for loop, you need to traverse it to len(array) -i -1 , because at the end of each iteration largest element would be at the end of the array.

Hope this answers your question!!
