我尝试过:



how to print this:

What I have tried:

<!DOCTYPE html>
<html>
<head>
	<title>reverse</title>
</head>
<body>
<script>
	var n=prompt("enter your limit");
	for(i=1;i<=n;i++)
	{
		document.write("<br>");
		for(j=1;j>=i;j++)
		{
			document.write("*");
		}
		}
</script>
</body>
</html>

推荐答案

// Outer Loop, which does control the column length
for (noOfColumns= limit; noOfColumns >=1; noOfColumns--)
{
   // here we have noOfColumns which means how many "*" we Need to print. 
   // So lets print from 1 to columns
   for (j= 1; j <= noOfcolumns; j++)
   {
      document.write("*");
   }
   // Current line is finished
   document.write("<br>"); 
}





我希望它有所帮助。请不要简单地复制和粘贴。试着理解它;)



I hope it helps. Please do not simply copy&paste. Try to understand it ;)

说不然,你有:

f(1)= 1,f(2)= 2,f(3)= 3,f(4)= 4,f(5)= 5

你想要

f(1)= 5,f(2)= 4,f(3)= 3,f(4)= 2,f(5)= 1

你不能设备公式pf f()?

这真的不复杂。

Said otherwise, you have:
f(1)= 1, f(2)= 2, f(3)=3, f(4)= 4, f(5)= 5
and you want
f(1)= 5, f(2)= 4, f(3)=3, f(4)= 2, f(5)= 1
Can't you device the formula pf f() ?
It is really not complicated.
