Problem 1533. Criss-Cross Verification: NHL

This Challenge is to verify a Criss-Cross matrix has no invalid words,contains all of the word set, and all are simply connected (Up/Down/Left/Right). Separation, UDLR, must exist between non-intersecting words. Diagonal is considered separate.

The word set is a cell array. The matrix is an array of Char with spaces being represented by '`', char(96), which is under the tilde on my keyboard.

Example:

Input:

dict={'abcd' 'cag'}

Achar=['abcd'
       '``a`'
       '``g`'];

Output: Validity (1 for Valid, 0 for Invalid)
