A very hard mathematic problemTime Limit: 2000/1000 MS (Java/Others) Memory Limit: 32768/32768 K (Java/Others)Total Submission(s): 10176 Accepted Submission(s): 3317 Problem Description Haoren is very good at solving mathematic problems. Today he is working a problem like this: Find three positive integers X, Y and Z (X < Y, Z > 1) that holds X^Z + Y^Z + XYZ = K where K is another given integer. Here the operator ^^ ̄ means power, e.g., 2^3 = 2 * 2 * 2. Finding a solution is quite easy to Haoren. Now he wants to challenge more: What¨s the total number of different solutions? Surprisingly, he is unable to solve this one. It seems that it¨s really a very hard mathematic problem. Now, it¨s your turn. Input There are multiple test cases. For each case, there is only one integer K (0 < K < 2^31) in a line. K = 0 implies the end of input. Output Output the total number of solutions in a line for each test case. Sample Input
Sample Output
Hint 9 = 1^2 + 2^2 + 1 * 2 * 2 53 = 2^3 + 3^3 + 2 * 3 * 3 Source | ||||||||||
