You are given an array of distinct integers arr and an array of integer arrays pieces, where the integers in pieces are distinct. Your goal is to form arr by concatenating the arrays in pieces in any order. However, you are not allowed to reorder the integers in each array pieces[i].
Return true if it is possible to form the array arr from pieces. Otherwise, return false.
\n
Example 1:
\n\n\nInput: arr = [15,88], pieces = [[88],[15]]\nOutput: true\nExplanation: Concatenate [15] then [88]\n\n\n
Example 2:
\n\n\nInput: arr = [49,18,16], pieces = [[16,18,49]]\nOutput: false\nExplanation: Even though the numbers match, we cannot reorder pieces[0].\n\n\n
Example 3:
\n\n\nInput: arr = [91,4,64,78], pieces = [[78],[4,64],[91]]\nOutput: true\nExplanation: Concatenate [91] then [4,64] then [78]\n\n\n
\n
Constraints:
\n\n1 <= pieces.length <= arr.length <= 100sum(pieces[i].length) == arr.length1 <= pieces[i].length <= arr.length1 <= arr[i], pieces[i][j] <= 100arr are distinct.pieces are distinct (i.e., If we flatten pieces in a 1D array, all the integers in this array are distinct).给你一个整数数组 arr ，数组中的每个整数 互不相同 。另有一个由整数数组构成的数组 pieces，其中的整数也 互不相同 。请你以 任意顺序 连接 pieces 中的数组以形成 arr 。但是，不允许 对每个数组 pieces[i] 中的整数重新排序。
如果可以连接 pieces 中的数组形成 arr ，返回 true ；否则，返回 false 。

示例 1：
\n\n\n输入：arr = [15,88], pieces = [[88],[15]]\n输出：true\n解释：依次连接\n\n[15]和[88]\n
示例 2：
\n\n\n输入：arr = [49,18,16], pieces = [[16,18,49]]\n输出：false\n解释：即便数字相符，也不能重新排列 pieces[0]\n\n\n
示例 3：
\n\n\n输入：arr = [91,4,64,78], pieces = [[78],[4,64],[91]]\n输出：true\n解释：依次连接\n\n[91]、[4,64]和[78]
\n\n
提示：
\n\n1 <= pieces.length <= arr.length <= 100sum(pieces[i].length) == arr.length1 <= pieces[i].length <= arr.length1 <= arr[i], pieces[i][j] <= 100arr 中的整数 互不相同pieces 中的整数 互不相同（也就是说，如果将 pieces 扁平化成一维数组，数组中的所有整数互不相同）\\u7248\\u672c\\uff1a \\u7f16\\u8bd1\\u65f6\\uff0c\\u5c06\\u4f1a\\u91c7\\u7528
