Given an m x n matrix, return all elements of the matrix in spiral order.

Example 1:
Input: [[1,2,3],[4,5,6],[7,8,9]]
Output: [1,2,3,6,9,8,7,4,5]
Constraints:

  • m==matrix.lengthm == \text{matrix.length}

  • n==matrix[0].lengthn == \text{matrix}[0].\text{length}

  • 1≤m,n≤101 \leq m, n \leq 10

  • −100≤matrix[i][j]≤100-100 \leq \text{matrix}[i][j] \leq 100

Input
arr =[[1,2,3],[4,5,6],[7,8,9]]
