Noonerized Spumbers

문제

Everyone has heard of spoonerisms, named after William Archibald Spooner, an Oxford professor who had a habit of swapping prefixes of words, often with comical results. "May I show you to your seat?" became "May I sew you to your sheet?" and "a crushing blow" became "a blushing crow."

Just imagine him as a student of arithmetic, occasionally swapping the prefixes of the numbers he was calculating with and then wondering why his equations never made any sense. For instance, when he writes:

what he really intended to write was:

(He swapped prefixes "$99$" and "$669669$" in the first and third numbers.) And when he writes:

what he really intended to write was:

(He swapped the prefix "$7272$" with the prefix "$6868$" in the first and second numbers.)

Grading homework from young Mr. Spooner is quite a challenge. Fleas pined a way to help!

입력

The input consists of a single line containing an expression of the form "$x+y=zx\; +\; y\; =\; z$" or "$x\ast y=zx\; *\; y\; =\; z$", where $xx$, $yy$, and $zz$ are positive integers less than $2^{31}2^\{31\}$. There will be single spaces surrounding the "$++$" and "$\ast *$" operators and the "$==$" sign. The expression will not be a mathematically correct equation.

출력

Output a mathematically correct equation consisting of the input line modified by swapping proper prefixes of two of the three numbers $xx$, $yy$, $zz$. (A proper prefix of a string $ss$ is a prefix that is neither empty nor equal to $ss$.) Separate the numbers, operators, and the "$==$" sign with single spaces. All integers in the correct equation will be non-negative and less than $2^{31}2^\{31\}$. There is guaranteed to be only one possible correct equation that can be formed by swapping proper prefixes.

92 + 2803 = 669495

6692 + 2803 = 9495

6891 * 723 = 4979753

7291 * 683 = 4979753
