Pro.ID21166 TitleGrade School Multiplication Title链接http://10.20.2.8/oj/exercise/problem?problem_id=21166 AC1 Submit2 Ratio50.00% 时间&空间限制描述An educational software company, All Computer Math (ACM), has a section on multiplication of integers. They want to display the calculations in the traditional grade school format, like the following computation of 432 Note well that the final product is printed without any leading spaces, but that leading spaces are necessary on some of the other lines to maintain proper alignment. However, as per our regional rules, there should never be any lines withtrailing white space. Note that the lines of dashes have length matching the final product. As a special case, when one of the digits of the second operand is a zero, it generates a single 0 in the partial answers, and the next partial result should be on the same line rather than the next line down. For example, consider the following product of 90040 ----------- 8000040 180000900 ----------- 18008090040 The rightmost digit of the second operand is a 0, causing a 0 to be placed in the rightmost column of the first partial product. However, rather than continue to a new line, the partial product of As a final special case, if there is only one line in the partial answer, it constitutes a full answer, and so there is no need for computing a sum. For example, a computation of 246 Your job is to generate the solution displays. 输入The input contains one or more data sets. Each data set consists of two positive integers on a line, designating the operands in the desired order. Neither number will have more than 6 digits, and neither will have leading zeros. After the last data set is a line containing only 输出Description An educational software company, All Computer Math (ACM), has a section on multiplication of integers.

You should use a 64-bit type (i.e., a long in Java, or a long long in C++).
