                 ['C', 'B', 'C', 'A'],
                 ['B', 'A', 'A', 'D'],
                 ['D', 'B', 'B', 'C'])
      $str = 'BDCA'
Output: true

Example 2

Input: @chars = (['A', 'A', 'B', 'B'],
                 ['C', 'C', 'B', 'A'],
                 ['C', 'A', 'A', 'A'],
                 ['B', 'B', 'B', 'B'])
      $str = 'ABAC'
Output: false

Example 3
