Big Math  - 3 Points

As the experienced programmer(s) on board, you've been asked to show some of the new recruits some of what we do around here.

We had them take a little quiz before asking you, and unfortunately they're not the brightest group we've ever had. They all need a little arithmetic review. None of them were able to complete long multiplication! Yikes!

Your first teaching task will be to write a program to show them how long multiplication works. Since we do some heavy duty math, let's show them the work and everything, and the product will be no larger than a 16-bit signed integer.

Input Format
Each input file might have multiple products.
Each case will have only two lines containing two positive integers A & B.

(Remember that the product will be no larger than a 16-bit signed integer.)

All sets will end with a -1.

The input file will be called jin11.txt.

Output Format
For each test case output the long multiplication work as:
                <A>
x              <B>
----------------
  <subMultiple1>
  <subMultiple2>
  ...
+ <subMultipleN>
----------------
  <--Product--->


Example
Input
2
8
65
123

    65
x  123
------
   195
  130
+ 65
------
