Write a program that finds and displays all pairs of 5-digit numbers that between them use the digits0 through 9 once each, such that the first number divided by the second is equal to an integerN, where $2\le N \le 79$ . That is,

abcde / fghij = N

where each letter represents a different digit. The first digit of one of the numerals is allowed to be zero.

Each line of the input file consists of a valid integer N. An input of zero is to terminate the program.

Your program have to display ALL qualifying pairs of numerals, sorted by increasing numerator (and, of course, denominator).

Your output should be in the following general form:

xxxxx / xxxxx = N

In case there are no pairs of numerals satisfying the condition, you must write ``There are no solutions forN.". Separate the output for two different values of N by a blank line.

There are no solutions for 61.79546 / 01283 = 62

94736 / 01528 = 62

这道非常简单的题让我花了几个小时才搞定，还专门下载了文本比较软件比较我的和官方的答案。原因就是两个答案之间要有一行空格，

而答案的最后一行是不加一行空格的。很奇葩的题目。但仔细读下题Separate the output for two different values of N by a blank line.

只说了两行答案之间要有空格，并没有说答案后面也要加一行空格。SO..
