Problem Description
For decades, scientists have wondered whether each of the numbers from 0 to 100 could be represented as the sum of three cubes, where a cube is the same number multiplied together three times.
42 was the last number without a proven solution — until now.
The solution is (−80538738812075974)3+804357581458175153+126021232973356313=42
Now, Yen-Jen is suspicious of the existence of other solutions. But, the solutions are not so trivial to find out.
Yen-Jen wants to find out easysolutions first. That is, for the equation a3+b3+c3=xYen-Jen wants to find out at least one solution for each integer xx in [0,200],where |a|,|b|,|c|≤5000.
Since Yen-Jen is still busy preparing the test data of some(this?) problem, pleasehelp him find out at least one solution for each xx or tell him that thesolution doesn't exist when |a|,|b|,|c|≤5000.
Input
The first line contains an integer TT indicating the number of xx to bechecked.Following TT lines each contains one integer xx.
- 1≤T≤10
- 0≤x≤200
Output
For each test case, output one line containing three space-separated integers a,b,ca,b,c such that a3+b3+c3=x and |a|,|b|,|c|≤5000. If thesolution doesn't exist, output impossible
.
Sample Input
2 1 2
Sample Output
1 1 -1 1 1 0
这道题的答案范围x是0~200。但是需要枚举3个变量a,b,c且每个范围都是-5000~5000.
因此不管是什么方法应该TLE是跑不了(没错这竟然是一道不打表过不了的题(应该吧))
注意5000的3次还需要用到long long。
然后a,b,c三个变量的关系要么3正,要么2正1负要么1正2负。(不过3正好像也可以去掉……因为包含其中了?)
具体代码看这位大佬的吧qwq(里面有unordered_map和文件freopen)
