## 无向图最小环计数 {pending}

### 例题 - [Luogu P6175] 无向图的最小环问题

给定一张无向图, 求图中一个至少包含 $3$ 个点的环, 环上的节点不重复, 并且环上的边的长度之和最小. 该问题称为无向图的最小环问题. 在本题中, 你需要输出最小的环的边权和. 若无解, 输出 `No solution.`

#### 输入格式

第一行两个正整数 $n,m$ 表示点数和边数

接下来 $m$ 行, 每行三个正整数 $u,v,d$, 表示节点 $u,v$ 之间有一条长度为 $d$ 的边

#### 输出格式

输出边权和最小的环的边权和. 若无解, 输出 `No solution.`

#### 样例输入 #1

```input1
5 7
1 4 1
1 3 300
3 1 10
1 2 16
2 3 100
2 5 15
5 3 20
```

#### 样例输出 #1

```output1
61
```

#### 提示

样例解释: 一种可行的方案: $1-3-5-2-1$

对于 $20\%$ 的数据, $n,m \leq 10$

对于 $60\%$ 的数据, $m\leq 100$

对于 $100\%$ 的数据, $1\le n\leq 100$, $1\le m\leq 5\times 10^3$, $1 \leq d \leq 10^5$

**无解输出包括句号**

若 $T\in\textrm{SO}(3)$, 即 $\det T=1$, 则称该合同变换 $\mathcal{T}$ 为 **刚体运动**, 否则称该合同变换 $\mathcal{T}$ 为 **反向刚体运动**

简单来说就是: 刚体运动是旋转和平移的复合, 而反向刚体运动是反射变换后的刚体运动
