python实现：利用冒泡排序
def minNum(array):
res=""
array=[str(arr) for arr in array]
for i in range(len(array)):
for j in range(i,len(array)):
if array[i]+array[j]<array[j]+array[i]:
array[i],array[j]=array[j],array[i]
for arr in array:
res+=arr
return int(res)
if __name__=="__main__":
array=[123,321,111]
print(minNum(array))
利用sort和sorted：
def minNum(array):
res=""
array=[str(arr) for arr in array]
# array.sort(reverse=True)
array=sorted(array,reverse=True)
for arr in array:
res+=arr
return int(res)
if __name__=="__main__":
array=[123,321,111]
print(minNum(array))
