求此题详解，多谢大佬！

Answer 1

public static void function(int number) {
int maxMask=1;
int length=1;
for(;number/maxMask>10;maxMask*=10,length++);
System.out.println(length);
int[] array=new int[length];
for(int i=0;i<length;maxMask/=10,i++) {
System.out.print(number/maxMask);
array[i]=number/maxMask;
number-=array[i]*maxMask;
if(i!=length-1)
System.out.print(" ");
}
System.out.println();
for(int i=length-1;i>-1;i--)
System.out.print(array[i]);
}
