Xiao Keke has $T$ calculation problems of the form $a + b = c$. You need to check whether she got each problem correct.

The first line contains a positive integer $T$. The next $T$ lines each contain an expression in the form `a+b=c`. It is guaranteed that the input format is correct, the numbers have no leading zeros, and there are no spaces between numbers and operators. See the sample for the exact format.

Output $T$ lines. If the $i$-th expression is correct, output `Right!` on the $i$-th line; otherwise, output `Wrong!` on the $i$-th line.

### Sample 1 Explanation Note from the problem porter: To avoid insulting everyone’s intelligence, the sample will not be explained. (There is no sample explanation in the setter’s PDF either.) ### Constraints For $40\%$ of the testdata, $a = b = 1$ and $c = 2$. For $80\%$ of the testdata, $a,b,c \le 9$. For $100\%$ of the testdata, $1 \le T \le 10$ and $1 \le a,b,c \le 99$. Translated by ChatGPT 5
