题目：

想法：

将输入的字符串中每个字符都转为ASCII码，再通过快速排序进行排序并输出

input_str = input()
input_list = [int(ord(l)) for l in input_str]def partition(arr, low, high):i = low - 1pivot = arr[high]for j in range(low, high):if arr[j] <= pivot:i += 1arr[j], arr[i] = arr[i], arr[j]arr[i+1], arr[high] = arr[high], arr[i+1]return i+1def quick_sort(arr, low, high):if low < high:pi = partition(arr, low, high)quick_sort(arr, low, pi-1)quick_sort(arr, pi+1, high)return arrresult = quick_sort(input_list, 0, len(input_list)-1)
result_str = ""
for r in result:result_str += chr(r)
print(result_str)
