Write a function `IsSorted` that returns `true`, if the slice of `int` is sorted, and that returns `false` otherwise.
Write a function `IsSorted` that returns `true`, if the slice of `int` is sorted, otherwise returns `false`.
The function passed in parameter returns a positive `int` if `a` (the first argument) is superior to `b` (the second argument), it returns `0` if they are equal and it returns a negative `int` otherwise.
The function passed in the parameter returns a positive `int` if `a` (the first argument) is greater than to `b` (the second argument), it returns `0` if they are equal and it returns a negative `int` otherwise.
To do your testing you have to write your own `f` function.
