CF794B.Cutting Carrot

Igor the analyst has adopted n little bunnies. As we all know, bunnies love carrots. Thus, Igor has bought a carrot to be shared between his bunnies. Igor wants to treat all the bunnies equally, and thus he wants to cut the carrot into n pieces of equal area.

Formally, the carrot can be viewed as an isosceles triangle with base length equal to 1 and height equal to h. Igor wants to make n - 1 cuts parallel to the base to cut the carrot into n pieces. He wants to make sure that all n pieces have the same area. Can you help Igor determine where to cut the carrot so that each piece have equal area?

Illustration to the first example.

分析员伊戈尔收养了 $n$ 只小兔子。众所周知，兔子喜欢吃胡萝卜。因此，伊戈尔买了一根胡萝卜，准备分给他的兔子们。伊戈尔希望公平地对待所有兔子，于是他打算将这根胡萝卜切成 $n$ 块面积相等的部分。

形式化地说，这根胡萝卜可视为一个底边长度为 $1$、高为 $h$ 的等腰三角形。伊戈尔计划作 $n-1$ 次平行于底边的切割，将胡萝卜分成 $n$ 块，并确保每一块的面积都相等。你能帮伊戈尔确定切割位置，使得每一块面积都相等吗？

第一个样例的示意图。

The first and only line of input contains two space-separated integers, n and h (2 ≤ n ≤ 1000, 1 ≤ h ≤ 105).

输入仅有一行，包含两个以空格分隔的整数 $n$ 和 $h$（$2 \le n \le 1000$，$1 \le h \le 10^5$）。

The output should contain n - 1 real numbers _x_1, _x_2, ..., x__n - 1. The number x__i denotes that the i-th cut must be made x__i units away from the apex of the carrot. In addition, 0 < _x_1 < _x_2 < ... < x__n - 1 < h must hold.

Your output will be considered correct if absolute or relative error of every number in your output doesn't exceed 10 - 6.

Formally, let your answer be a, and the jury's answer be b. Your answer is considered correct if .

输出应包含 $n-1$ 个实数 $x_1,\,x_2,\,\dots,\,x_{n-1}$。其中，数 $x_i$ 表示第 $i$ 次切割必须在距胡萝卜顶点 $x_i$ 个单位处进行。此外，还需满足 $0 < x_1 < x_2 < \dots < x_{n-1} < h$。

若输出中每个数的绝对误差或相对误差均不超过 $10^{-6}$，则你的输出将被视为正确。

形式化地，设你的答案为 $a$，评测机的答案为 $b$。当满足 时，你的答案即被视为正确。
