Given two n x n binary matrices mat and target, return true if it is possible to make mat equal to target by rotating mat in 90-degree increments, or false otherwise.
Example 1:
Input: mat = [[0,1],[1,0]], target = [[1,0],[0,1]] Output: true Explanation: We can rotate mat 90 degrees clockwise to make mat equal target.
Example 2:
Input: mat = [[0,1],[1,1]], target = [[1,0],[0,1]] Output: false Explanation: It is impossible to make mat equal to target by rotating mat.
Example 3:
Input: mat = [[0,0,0],[0,1,0],[1,1,1]], target = [[1,1,1],[0,1,0],[0,0,0]] Output: true Explanation: We can rotate mat 90 degrees clockwise two times to make mat equal target.
Constraints:
n == mat.length == target.lengthn == mat[i].length == target[i].length1 <= n <= 10mat[i][j] and target[i][j] are either 0 or 1.
