1886 - Determine Whether Matrix Can Be Obtained By Rotation.Easy
Given two
n x n
binary matricesmat
andtarget
, returntrue
if it is possible to makemat
equal totarget
by rotatingmat
in 90-degree increments , orfalse
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]
andtarget[i][j]
are either0
or1
.
