Jquery hide & show to build quiz

问题

i'm trying to make a simple quiz using jquery hide & show functions , first i created some divs elements wich will be the questions + the last elements will contain a text & a button to watch result (there will be no result) ; i'm using two buttons : next & prev .

So the things i can't do on my own are :

1- hide the two buttons when they show the last div (Of the result !) ;

2-make the prev buttons stop on the first question .

3- how i can implement bootstrap radio options with Jquery to store answers & show them at the last on the click of button.

$(document).ready(function(){
    $(".divs div").each(function(e) {
        if (e != 0)
            $(this).hide();
    });

    $("#next").click(function(){
        if ($(".divs div:visible").next().length != 0)
            $(".divs div:visible").next().show().prev().hide();
        else {
            $(".divs div:visible").hide();
            $(".divs div:first").show();
        }
        return false;
    });

    $("#prev").click(function(){
        if ($(".divs div:visible").prev().length != 0)
            $(".divs div:visible").prev().show().next().hide();
        else {
            $(".divs div:visible").hide();
            $(".divs div:last").show();
        }
        return false;
    });
});

<div class="divs">
     <div class="cls1">1</div>
     <div class="cls2">2</div>
     <div class="cls3">3</div>
     <div class="cls4">4</div>
     <div class="cls5">5</div>
     <div class="cls6">6</div>
     <div class="cls7">7</div>
 </div>
 <a id="next">next</a>
 <a id="prev">prev</a>

Thanks in advance guys !
