***** CLARIFICATIONS *****
NOTE: The memory limit is lower than the individual contest.  The limit now
is 32MB.

(problem 1): Copy is 'c', not 'd'.

(problem 1): When we discuss deleting, modifying, or copying, the character
that must be consumed is the leftmost character in the string.

(problem 3): The last sentence of the third paragraph should be:
"That is, the hound first considers whether to go West; then, if the
expected distance if it goes South is better or within 1e-5, the hound
considers going South; then East; then North; then staying still."

(problem 3): N*exp(((x-x')^2 + (y-y')^2)/(2 * sigma^2)) should be
N*exp(-((x-x')^2 + (y-y')^2)/(2 * sigma^2)) (there's a missing minus sign).

(problem 5): Output a dot ('.') in any cell where it is impossible to
deduce whether there is a mine.
