Interview Code

This is a test problem from Method Industries. Attached is my file on how to sovlve the problem.

Java is not my main language but it is a language I am wanting to learn more about.

Write a function that takes three Integer numbers Number1, Number2, and Number3, and determines if there is a mathematical operation that will make Number1 (operation) Number2 equal to Number3. If one or more of the 4 common mathematical operations (+,-,,/) can complete the function, return the String representation of the mathematical function. If none of the 4 mathematical operations can make the statement true, return the String "None". For instance: public String mathFunction(1,2,3) returns "+", public String mathFunction(2,2,4) returns "+", (+ and ) public String mathFunction(3,-3,-9) returns "", public String mathFunction(1,2,-1) returns "-", public String mathFunction(3,3,1) returns "/", public String mathFunction(7,1,11) returns "None". You need not use Scanner to input numbers from the user if you would not like to. You can simply write a function that takes the appropriate parameters and pass those parameters in the main method. For extra credit, write tests using Junit.
