Good morning! Here's your coding interview problem for today.

This problem was asked by Coursera.

Given a 2D board of characters and a =
word, find if the word exists in the grid.

The word can be constructed =
from letters of sequentially adjacent cell, where
"adjacent" cells are =
those horizontally or vertically neighboring. The same
letter cell may not be used more than once.

For example, given the =
following board:

[
  ['A','B','C','E'],
  ['S','F','C','S'],
  ['A','D','E','E']
]


exists(board, "ABCCED") returns true,exists(board, =
"SEE") returns true,
exists(board, "ABCB") returns false.
