php - Why does this style effect all the tags even though I closed it, when I use printf -


i'm studing php , tried color <h1> tag. previous style influenced <h1> tag.

this code: 

<?php echo "<span style='color:#$lets'>hello world!</span";  echo "<br /> <br />";   printf("<h1 stlye='color:#%x%x%x'>hello world! again.</h1>",200,250,100);  ?>

you haven't closed span tag , have typo, should style instead of stlye. 

<?php echo "<span style='color:#$lets'>hello world!</span>";  echo "<br /> <br />";   printf("<h1 style='color:#%x%x%x'>hello world! again.</h1>",200,250,100);  ?>

i've seen in various stackoverflow answers can nth largest element in list doing var nthfromtop = items.orderbydescending().skip(n-1).first(); but wouldn't work if there no duplicates in list? if list contains duplicates, there way nth largest element (or set of elements) using linq? if not, efficient way in c#? to set of items equal nth largest item you'll need group items, order groups, , decrement n group size while n positive. when n reaches zero, you've hit group containing nth largest item. public static ienumerable<t> foo<t>(this ienumerable<t> source, int n) { return source.groupby(x => x) .orderbydescending(group => group.key) .skipwhile(group => { n -= group.count(); return n > 0; }) .first(); }
