CF12B.Correct Solution?

One cold winter evening Alice and her older brother Bob was sitting at home near the fireplace and giving each other interesting problems to solve. When it was Alice's turn, she told the number n to Bob and said:

—Shuffle the digits in this number in order to obtain the smallest possible number without leading zeroes.

—No problem! — said Bob and immediately gave her an answer.

Alice said a random number, so she doesn't know whether Bob's answer is correct. Help her to find this out, because impatient brother is waiting for the verdict.

一个寒冷的冬夜，爱丽丝和她年长的哥哥鲍勃正坐在家中的壁炉旁，互相出一些有趣的题目来解答。轮到爱丽丝时，她告诉鲍勃一个数字 $n$，并说道：

— 重新排列这个数字的各位数字，得到不含前导零的最小可能的数。

— 没问题！ — 鲍勃立刻给出了答案。

爱丽丝随口说出了一个数字，因此她并不知道鲍勃的答案是否正确。请帮她验证一下，因为性急的哥哥正在等待裁决结果。

The first line contains one integer n (0 ≤ n ≤ 109) without leading zeroes. The second lines contains one integer m (0 ≤ m ≤ 109) — Bob's answer, possibly with leading zeroes.

第一行包含一个整数 $n$（$0 \leq n \leq 10^9$），不含前导零。
第二行包含一个整数 $m$（$0 \leq m \leq 10^9$）—— Bob 的答案，可能含前导零。

Print OK if Bob's answer is correct and WRONG_ANSWER otherwise.

如果 Bob 的答案正确，输出 OK；否则输出 WRONG_ANSWER。
