COCI 2007/2008, Contest #5

Task TRI

Little Mirko wrote into his math notebook an equation containing three positive integers, the equals sign and one of the four basic arithmetic operations (addition, subtraction, multiplication and division).

During another class, his friend Slavko erased the equals sign and the operations from Mirko's notebook.

Help Mirko by reconstructing the equation from the three integers.

Input

The first line of input contains three integers less than 100, separated by spaces.

Note: The input data will guarantee that a solution, although not necessarily unique, will always exist.

Output

On a single line, output a valid equation containing the three integers (in the same order), an equals sign and one of the four operations. If there are multiple solutions, output any of them.

Examples

Input

5 3 8

Output

5+3=8

Input

5 15 3

Output

5=15/3

how to add a string and integer? just wondering.

I'm not sure what you mean to ask, so I'll go through a couple (all code in c++)

You can concatenate a string and an integer by converting the integer to a string:

"this is " + to_string(3) => "this is 3"

You can add a string to an integer by converting the string to an integer:

stoi("32") + 3 => 35

You can add 2 integers together using the + operator

3 + 3 => 6

And finally, you can add 2 strings using string addition algorithms (which are a bit too complex for a comment)

myStringAdd("32", "32") => 64
