sc(2,2,4) should return "2+2=4" or "2*2=4" or "4/2=2" or "4-2=2"

sc(6,2,3) should return "2*3=6" or "3*2=6" or "6/2=3" or "6/3=2"

Return one of the possible answer, you can pass the test.

If there is no equation between a,b,c, return ""

You code length limit is 120 chars.

Code length calculation

In javascript, we can't get the user's real code, we can only get the system compiled code. Code length calculation is based the compiled code.

For example:

If you typed sc=x=>x+1
after compile, it will be:sc=function(x){return x+1;}
