# Problem C

Jednakost

While browsing a math book, Mirko found a strange equation of the form $A=S$. What makes the equation strange is that $A$ and $S$ are not the same. Mirko realized that the left side of the equation should have addition operations between some pairs of digits in $A$.

Write a program that inserts the **smallest number** of addition operations on the
left side to make the equation correct. The numbers in the
corrected equation may contain arbitrary amounts of leading
zeros.

## Input

The first line contains the equation in the form
$A=S$. $A$ and $S$ will both be positive integers
without leading zeros. They will be different. $A$ will contain at most $1000$ digits. $S$ will be less than or equal to
$5000$. **Note:** The input data will guarantee that a
solution, although not necessarily unique, will always
exist.

## Output

Output the corrected equation. If there are multiple solutions, output any of them.
