+我们可以用一个长度为 $10$ 的数组 $\text{cnt}$ 来记录每个数字的第一个数字出现的次数。

+遍历数组 $\text{nums}$，对于每个数字 $x$，我们枚举 $0$ 到 $9$ 的每个数字 $y$，如果 $\text{cnt}[y]$ 不为 $0$ 且 $\text{gcd}(x b\mod 10, y) = 1$，则答案加上 $\text{cnt}[y]$。然后，我们将 $x$ 的第一个数字出现的次数加 $1$。
+
+遍历结束后，返回答案即可。
+
+时间复杂度 $O(n \times (k + \log M))$，空间复杂度 $O(k + \log M)$。其中 $n$ 为数组 $\text{nums}$ 的长度，而 $k$ 和 $M$ 分别表示数组 $\text{nums}$ 中的数字的种类以及最大值。

-### Solution 1
+### Solution 1: Counting
+
+We can use an array $\text{cnt}$ of length $10$ to record the count of the first digit of each number.
+
+Iterate through the array $\text{nums}$. For each number $x$, we enumerate each digit $y$ from $0$ to $9$. If $\text{cnt}[y]$ is not $0$ and $\text{gcd}(x \mod 10, y) = 1$, then the answer is incremented by $\text{cnt}[y]$. Then, we increment the count of the first digit of $x$ by $1$.
+
+After the iteration, return the answer.
+
+The time complexity is $O(n \times (k + \log M))$, and the space complexity is $O(k + \log M)$. Here, $n$ is the length of the array $\text{nums}$, while $k$ and $M$ respectively represent the number of distinct numbers and the maximum value in the array $\text{nums}$.
