Problem Description
Given two integers n and m, count the number of pairs of integers (a,b) such that 0 < a < b < n and (a^2+b^2 +m)/(ab) is an integer.
This problem contains multiple test cases!
The first line of a multiple input is an integer N, then a blank line followed by N input blocks. Each input block is in the format indicated in the problem description. There is a blank line between input blocks.
The output format consists of N output blocks. There is a blank line between output blocks.

The output format consists of N output blocks. There is a blank line between output blocks.
Input
You will be given a number of cases in the input. Each case is specified by a line containing the integers n and m. The end of input is indicated by a case in which n = m = 0. You may assume that 0 < n <= 100.
Output
For each case, print the case number as well as the number of pairs (a,b) satisfying the given property. Print the output for each case on one line in the format as shown below.
Sample Input
110 120 330 40 0
Sample Output
Case 1: 2Case 2: 4Case 3: 5

奇坑无比的一道题!!!
WA了好多次,看了好几遍题目才整明白!!!
前面那个“1”表示下面有0 0 之前的一个大组测试数据。
所以,一大组测试数据之前的一个整数表示有几个大组包含若干小组。
还要注意,输出空行。
0 0
