<p>Great Solution. But how does the break work in this case? I mean how exactly this break stops the While Loop, because it should break when if statement is True???</p>

<p>`break` breaks the `for` loop, of course. If it doesn't, then the `else` executes, and `return` breaks the `while` loop. Simple. ;-)</p>
