HS08EQ - Amazing equality
The definition of a perfect number is about 2300 years old. A perfect number is defined as a positive integer which is the sum of its proper positive divisors, that is, the sum of the positive divisors excluding the number itself. What can we get if, in the sum, we replace each divisor by its square? You can prove that there is no such number. But there are many numbers for which the sum of some divisors' squares is equal to n, so n=d12+d22+...+dk2, where d1, d2, ...,dk are distinct (positive) divisors of n. You have to count how many times this happens. For example: the divisors of n=120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120. And there are exactly two amazing equalities:
120=22+42+102
120=22+42+62+82
Input
The first number is T, denoting the number of test cases (T<1000). T lines follow, each of which contains one positive integer (n<1010).
Output
Output T lines, the answer for each n.
Example
Input: 6 120 720 1000 1200 92070 123618780 Output: 2 13 0 10 6448 292

I think that all the submitted solutions will get TLE or WA (the answer can be >= 2^64)

Why are the test cases so weak that some people used Brute Force and got passed? Last edit: 2013-12-24 11:16:48 |
