    1886 - Determine Whether Matrix Can Be Obtained By Rotation.

    Easy

    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.length

    • n == mat[i].length == target[i].length

    • 1 <= n <= 10

    • mat[i][j] and target[i][j] are either 0 or 1.
