JavaScript

// Hunting flags in the Document
//
// Using jQuery
//
// Find the three flags (they have "FLAG" text inside them)
// and move their containing elements into the #bucket
//
// Hint: Expect to use
//     $(selector)
//     .append()
//     .prepend()

// Note: I'm wrapping this in the DOM on-ready event for you
// So that it runs AFTER the page is loaded and ready
$(document).ready(function() {

    var flags = [];
  
    var flag1 = $("div.main > ul > li:nth-child(2)");
    flags.push(flag1);
    
    var flag2 = $(".flag");
      
    flags.push(flag2);
    var flag3 = $(".footer div:contains('FLAG')"); 
                 
    flags.push(flag3);
	
    var bucket = $("#bucket");
    
	$.each( flags, function(i,flag){
    	bucket.append( flag );
    });
   
});
    
// bonus: write a function to crawl the entire document and search for the "FLAG" text, and do the job for you.
