The cave, called “Mass of Darkness”, had been a agitating point of the evil, but the devil king and all of his soldiers were destroyed by the hero and the peace is there now.
One day, however, the hero was worrying about the rebirth of the devil king, so he decided to ask security agency to patrol inside the cave.
The information of the cave is as follows:
The following is how the security agent patrols:
Your task is to write a program to check whether the agent can finish his patrol without dying.
The input is a sequence of datasets. Each dataset is given in the following format:
HPinit HPmax R C a1,1 a1,2 . . . a1,C a2,1 a2,2 . . . a2,C . . . aR,1 aR,2 . . . aR,C T [A-Z] d1 [A-Z] d2 . . . [A-Z] dT S [UDLR] n1 [UDLR] n2 . . . [UDLR] nS P p1 p2 . . . pP
The first line of a dataset contains two integers HPinit and HPmax (0 < HPinit ≤ HPmax ≤ 1000), meaning the agent’s initial hit point and the agent’s maximum hit point respectively.
The next line consists of R and C (1 ≤ R, C ≤ 100). Then, R lines which made of C characters representing the information of the cave follow. The character ai,j means there are the trap of type ai,j in i-th row and j-th column, and the type of trap is denoted as an uppercase alphabetic character [A-Z].
The next line contains an integer T, which means how many type of traps to be described. The following T lines contains a uppercase character [A-Z] and an integer di (0 ≤ di ≤ 1000), representing the type of trap and the amount of damage it gives.
The next line contains an integer S (0 ≤ S ≤ 1000) representing the number of sequences which the hero specified as the agent’s patrol route. Then, S lines follows containing a character and an integer ni ( ΣSi=1 ni ≤ 1000), meaning the direction where the agent advances and the number of step he takes toward that direction. The direction character will be one of ‘U’, ‘D’, ‘L’, ‘R’ for Up, Down, Left, Right respectively and indicates the direction of the step.
Finally, the line which contains an integer P (0 ≤ P ≤ 12) meaning how many type of potions the agent has follows. The following P lines consists of an integer pi (0 < pi ≤ 1000) which indicated the amount of hit point it recovers.
The input is terminated by a line with two zeros. This line should not be processed.
For each dataset, print in a line “YES” if the agent finish his patrol successfully, or “NO” otherwise.
If the agent’s hit point becomes less than or equal to 0 at the end of his patrol, the output should be “NO”.
