Description

XiaoA is a lovely boy who likes designing some digital product.One day, he met XiaoB who is XiaoA's little girl friend and told her that his new product had came out.It's a calculator which can do add($+$) opeartion and sub($-$) operation between nonnegative numbers.

Actually, XiaoA's calculator is very low-grade.However, XiaoB is not willing to make XiaoA disappoint, and praised XiaoA's talent all the same.

The calculator has three $K$-digit register, named Ra, Rb and Rc.You can input a nonnegative decimal number to the register Ra and Rb, which will be stored in the binary base.For example, if $K$ is $8$ then $99$ stored as 01100011, and $147$ stored as 10010011.Now a problem is that the value will change after storing in the register for a large decimal number. For instance, $523$ will be stored as 00001011 for $K=8$. Yes! Because $523$ is overflow for this $8$-digit register.

The operation of the calculator is $R_a + R_b = R_c$ and $R_a - R_b = R_c$. In the sub operation , it should be guaranteed that the number stored in $R_a$ is not smaller in decimal base than that in $R_b$ , otherwise XiaoA will roar, it's too hard!.

Since XiaoA can do it, how about you?

Input

In the first line is $N$ ($N\leq 100$), which is the number of test cases.

For each of the next $N$ lines, the first is a number $K$($1\leq K\leq 16$), then there is a operation either $A + B$ or $A - B$, where $A$(stored in $R_a$) and $B$(stored in $R_b$) are nonnegtive decimal integers ($0\leq A, B\leq 10^7$).

Output

For each case, you should output one line.

First, output Case #C: , where $C$ is the number of the test case, from $1$ to $T$.

Then, if it is a sub operation and the number stored in $R_a$ is smaller in decimal base than that in $R_b$, you should output Maybe , it is really too hard, hha!, else you should output the number which is stored in $R_c$ in decimal base.

Samples

3
8 5 + 3
8 4 - 9
8 523 + 1

Case #1: 8
Case #2: Maybe , it is really too hard, hha!
Case #3: 12
