Description:
Coding 3min: Give me the equation

This is the simple version of Shortest Code series. If you need some challenges, please try the challenge version

#Task:
Give you three numbers:```a b c```,please return an equation(Operators include +,-,*,/), return type is string.

For example: 

```sc(1,2,3)``` should return ```"1+2=3"``` or ```"2+1=3"```  or  ```"3-2=1"```  or ```"3-1=2"```

```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 ```""```
