Python實現部分函數-SelectionSort(arr): 選擇排序法

#選擇排序法

方法一：

def selectionSort(arr):
    length = len(arr)
    for i in range(0,length-1):
        index = i
        for j in range(i+1,length):
            if arr[j]<arr[index]:
                tmp = arr[j]
                arr[j] = arr[index]
                arr[index]=tmp
    return arr

arr = [5, 3, 6, 2, 10]
print(selectionSort(arr))

方法二：

def FindSmallest(arr):
    smallest=arr[0]
    smallest_index=0
    for i in range(1,len(arr)):
        if arr[i] < smallest:
            smallest = arr[i]
            smallest_index = i
    return smallest_index

def SelectionSort(arr):
    new_arr=[]
    for i in range(len(arr)):
        smallest=FindSmallest(arr)
        new_arr.append(arr.pop(smallest))
    return new_arr

if __name__ == '__main__':
        arr = [5, 3, 6, 2, 10]
        print(SelectSortion(arr))
