Write a function named maxNumber. You are given 2 positive int values, a, and b. Your function should return the larger value that is in range 10. 20 inclusive. Else return 0 if neither is in the range.

Example maxNumber(11,19) returns 19

maxNumber (10,45) return 10. maxNumber (30,45) returns 0.

Please use an if function and provide an explanation. Thank you!!!
