java Programming Safe crackers Sal and Roscoe think they are so smart. They have cracked the code on a number of safes with 4-directional combinations. For every safe they crack, they remember the combination by constructing an "nx n" table with cell entries representing numbers and directions on a safe. What they didn't count on is your genius in cracking their system. For example, given this 4 x 4 table: 2D 1D 2L 2L 2D OPEN 1U 2R 1R 1R 1R 1U 1L 3U 1L 2U 2L 2D 1R 1R1R 1U 1U 2L 1D 2D 1L 2U 2R OPEN. Having cracked their system, you can now write a program to discover the combination of any safe Sal and Roscoe have cracked. . You have discovered that the 16-instruction sequence to open the safe is: 1L 3U
