1237. 找出给定方程的正整数解

代码：

class Solution {
    public List<List<Integer>> findSolution(CustomFunction customfunction, int z) {
        List<List<Integer>> list = new ArrayList<>();
        for (int i = 1; i <= 1000; i++)
        {
            if (customfunction.f(i, 1) > z) break;
            for (int j = 1; j <= 1000; j++)
            {
                if (customfunction.f(i, j) == z) {
                    List<Integer> nums = new ArrayList<Integer>();
                    nums.add(i);
                    nums.add(j);
                    list.add(nums);
                }
                else if (customfunction.f(i, j) > z) break;
            }
        }
        return list;
