Description

Teacher Wang is teaching basic arithmetic operations. The careful teacher has collected $i$ mental arithmetic problems that students often get wrong and wants to organize them into a practice set. Arranging these problems is a tedious task, so he wants to use a computer program to improve efficiency. Teacher Wang hopes to minimize input work - for example, for the expression $5+8$, he only needs to input $5$ and $8$. The output should be detailed enough to facilitate later typesetting, such as outputting $5+8=13$ and the total length of the expression $6$ for the above input. Teacher Wang has entrusted this honorable task to you, please help him implement this functionality.

Input Format

The first line contains an integer $n$ ($1≤n≤50$).
The next $n$ lines contain the expressions to be input, each line may have either three or two numbers.
If a line has three numbers, the first number indicates the operation type: $a$ for addition, $b$ for subtraction, $c$ for multiplication, followed by two numbers $x$ and $y$ representing the operands.
If a line has two numbers $x$ and $y$, it means the operation type is the same as the previous problem, and these two numbers are the operands.
The data guarantees that the first expression has three numbers, and $0≤x,y<10000$.

Output Format

Output $2n$ lines. For each input expression, the first line outputs the complete expression and result, and the second line outputs the total length of the expression.
