Combining Pseudo-Classes in LESS

The ampersand is useful when working with pseudo-classes. See the example:

a {
	color: blue;
	&:hover {
		color: red;
	}
}

Compilation result:

a {
	color: blue;
}
a:hover { 
	color: red;
}

Tell me what the result of compiling the following code will be:

a.class {
	&:link {
		color: red;
	}
	&:visited {
		color: blue;
	}
	&:hover {
		color: green;
	}
}

Simplify the given code:

#block {
	width: 300px;
}
#block a:link, #block a:visited {
	color: red;
}
#block a:hover {
	color: blue;
}
