Grenade in the Lake!!

$N$ people including Ukje stand in a row on a number line. Ukje stands at $0$, and the positions are given from left to right in nondecreasing order. A person with range $r$ can throw the grenade to anyone whose distance is at most $r$, and anyone can catch a grenade thrown at them. When several people share one position, any one of them can catch it and throw it onward.

The grenade starts with Ukje. The game ends quietly when the $N$th person from the left, the rightmost one, receives it. Everyone cooperates, so the game succeeds when at least one relay path reaches that last person. When the grenade falls to the ground, the game fails.

The first line holds $N$ with $1 \le N \le 30000$.

The second line holds $N$ positions from left to right. The first one is Ukje at $0$. Each position is an integer with $0 \le x \le 1000000$.

When $N > 1$, the third line holds $N - 1$ ranges in the same order. The first range belongs to Ukje, and the rightmost person is excluded. Each range is an integer with $0 \le r \le 1000000$. When $N = 1$, the third line is absent.

When the last person can receive the grenade, print 권병장님, 중대장님이 찾으십니다. Otherwise print 엄마 나 전역 늦어질 것 같아. Print exactly one line including the trailing newline.
