declare const example: {
    foo: {
        bar: {
            a: string;
        };
        baz: {
            b: number
            c: number
        }
    };
}

// Possible solutions: 
// []
// ['foo']
// ['foo', 'bar']
// ['foo', 'bar', 'a']
// ['foo', 'baz']
// ['foo', 'baz', 'b']
// ['foo', 'baz', 'c']
