FOO BAR FIX KATA

Statement:

This project implement a function String compute(String) which implements the following rules.

Step 1:

• If the number is divisible by 3, write “Foo” instead of the number
• If the number is divisible by 5, add “Bar”
• If the number is divisible by 7, add “Qix”
• For each digit 3, 5, 7, add “Foo”, “Bar”, “Qix” in the digits order.
• Add a description for each of the above cases

Examples:

1  => 1
2  => 2
3  => FooFoo (divisible by 3, contains 3)
4  => 4
5  => BarBar (divisible by 5, contains 5)
6  => Foo (divisible by 3)
7  => QixQix (divisible by 7, contains 7)
8  => 8
9  => Foo (divisible by 3)
10 => Bar (divisible by 5)
13 => Foo (contains 3)
15 => FooBarBar (divisible by 3, divisible by 5, contains 5)
33 => FooFooFoo (divisible by 3, contains two 3)
53 => FooBar (contains 3,contains 5)

Step 2:
We have a new business request: we must keep a trace of 0 in numbers, each 0 must be replaced by char “*“.

Examples:

101   => 1*1
303   => FooFoo*Foo
105   => FooBarQix*Bar
10101 => FooQix**

Implementation:

this is a Spring Boot project providing one service which we can use to test the compute function.

• end-point path: localhost:8080/compute/{input}
• example : localhost:8080/compute/5

Run the project:

mvn spring-boot:run

Run the test and generate the JAR:

mvn clean package
