用Python怎么写产生30000个随机整数,用蛮力法进行选择排序和冒泡排序

可以使用Python的random模块来生成30000个随机整数:import random numbers = [random.randint(0, 30000) for _ in range(30000)] 用蛮力法进行选择排序:def selection_sort(numbers): for i in range(len(numbers)): min_index = i for j in range(i + 1, len(numbers)): if numbers[min_index] > numbers[j]: min_index = j numbers[i], numbers[min_index] = numbers[min_index], numbers[i] return numbers 用蛮力法进行冒泡排序:def bubble_sort(numbers): for i in range(len(numbers)): for j in range(len(numbers)-1-i): if numbers[j] > numbers[j+1]: numbers[j], numbers[j+1] = numbers[j+1], numbers[j] return numbers

用python随机产生30000个随机整数,用蛮力法进行选择排序
好的,下面是用 Python 进行选择排序的代码:
```python
import random
def selection_sort(arr):
for i in range(len(arr) - 1):
min_index = i
for j in range(i + 1, len(arr)):
if arr[j] < arr[min_index]:
min_index = j
arr[i], arr[min_index] = arr[min_index], arr[i]
return arr
# 用 random.sample() 随机生成 30000 个整数
rand_ints = random.sample(range(1, 100001), 30000)
# 调用 selection_sort() 函数对随机生成的数组进行排序
sorted_arr = selection_sort(rand_ints)
```
请注意,选择排序是一种比较低效的排序算法,当数据规模较大时,耗时可能会非常长。
用Python写随机产生3000个整数,分别用蛮力法和归治法和减治法进行排序
你可以使用 Python 的 `random` 模块来随机生成 3000 个整数。例如:
```
import random
numbers = [random.randint(1, 10000) for _ in range(3000)]
```
对于排序,你可以使用蛮力法、归并排序和快速排序。
蛮力法:
```
def brute_force_sort(numbers):
for i in range(len(numbers)):
for j in range(i+1, len(numbers)):
if numbers[i] > numbers[j]:
numbers[i], numbers[j] = numbers[j], numbers[i]
return numbers
```
归并排序:
```
def merge_sort(numbers):
if len(numbers) <= 1:
return numbers
mid = len(numbers) // 2
left = numbers[:mid]
right = numbers[mid:]
left = merge_sort(left)
right = merge_sort(right)
return merge(left, right)
def merge(left, right):
result = []
i = j = 0
while i < len(left) and j < len(right):
if left[i] < right[j]:
result.append(left[i])
i += 1
else:
result.append(right[j])
j += 1
result += left[i:]
result += right[j:]
return result
```
快速排序:
```
def quick_sort(numbers):
if len(numbers) <= 1:
return numbers
pivot = numbers[0]
left = [x for x in numbers[1:] if x <= pivot]
right = [x for x in numbers[1:] if x > pivot]
return quick_sort(left) + [pivot] + quick_sort(right)
```
