Max of Two

Create a function called max that takes two i32 values and returns the larger one. Test it with a few different pairs of numbers.

Expected output:

Max of 3 and 7 is 7
Max of 10 and 2 is 10
Max of 5 and 5 is 5

Hints:

• Define with fn max(a: i32, b: i32) -> i32
• Use an if expression to compare a and b
• Remember, if can be used as an expression in Rust: if a >= b { a } else { b }
