Question

Given an equation "x=y", for example, "111=12", you need to add pluses inside x to
make the equation correct. In our example "111=12", we can add one plus "11+1=12"
and the equation becomes correct. You need to find the minimum number of pluses to
add to x to make the equation correct. If there is no answer print - 1.
Note that the value of y won't exceed 5000. The numbers in the corrected equation may
contain arbitrary amounts of leading zeros.
