题目：从键盘输入1个正整数，把这个整数的各位数字重新组合， 形成一个位数不变的最大数和最小数，并计算最大数与最 小数的差。 例如：输入241897，重组后最大数为:987421，最小数为:124789， 差为:862632 输入240097，重组后最大数为:974200，最小数为:200479， 差为:773721def bubblesortDown(date): length = len(date) #**********SPACE********** for i in range【?】: for j in range(0,length-i-1): if(date[j]>date[j+1]): t = date[j] date[j] = date[j+1] date[j+1] = t m=0 if(date[m]=='0'): while(date[m]=='0'): #**********SPACE********** 【?】 else: date[0] = date[m] date[m] = '0' content = "".join(date) return content def bubblesortUp(date): length = len(date) for i in range(length-1): for j in range(length-1,i,-1): #**********SPACE********** if(date[j-1]【?】date[j]): t = date[j-1] #**********SPACE********** 【?】 date[j] = t content = "".join(date) return content def diss(a): list1=list(a) max = int(bubblesortUp(list1)) min = int(bubblesortDown(list1)) dis=max-min print("最大数为:{},最小数为:{},差为:{}".format(max,min,dis) ) def main(): num = input("请输入一个正整数：") diss(num); if __name__ == '__main__': main()

这是一个关于重新组合正整数的程序，它会根据输入的正整数，计算出重组后的最大数和最小数，并计算它们的差值。以下是这个程序的完整代码：

def bubblesortDown(date):
    length = len(date)
    for i in range(length):
        for j in range(0,length-i-1):
            if(date[j]>date[j+1]):
                t = date[j]
                date[j] = date[j+1]
                date[j+1] = t
    m=0
    if(date[m]=='0'):    
        while(date[m]=='0'):
            m += 1               
        else:
            date[0] = date[m]
            date[m] = '0'
    content = "".join(date)   
    return content

def bubblesortUp(date):
    length = len(date)
    for i in range(length-1):
        for j in range(length-1,i,-1):
            if(date[j-1]<date[j]):
                t = date[j-1]
                date[j-1] = date[j]
                date[j] = t
    content = "".join(date)
    return content

def diss(a):
    list1=list(a)
    max_num = int(bubblesortUp(list1))
    min_num = int(bubblesortDown(list1))
    diff = max_num - min_num
    print("最大数为:{},最小数为:{},差为:{}".format(max_num,min_num,diff) )
        
def main():
    num = input("请输入一个正整数：")
    diss(num);
    
if __name__ == '__main__':
    main()

你可以运行这个程序并输入一个正整数，它会输出重新组合后的最大数和最小数，并计算它们的差值。希望对你有帮助！
