i have made this in javascript to try and help me solve it - but its not 100% working can u help me with it?
| Code: | <script>
var size =3;
var start =1;
var step =1;
var row =1;
var col = (size + 1) / 2;
var count = 1;
var number = start;
while (count > size * size)
{
var ans=new Array("row","col");
ans = number;
number = number + step;
count = count + 1;
var newrow = row - 1;
if (newrow < 1)
{
newrow = size;
}
var newcol = col - 1;
if (newcol < 1)
{
newcol = size;
}
if (array(newrow,newcol) != array("",""))
{
newrow = row + 1;
newcol = col;
}
if (newrow > size)
{
newrow = 1;
}
row = newrow
col = newcol
document.write("newrow:" + newrow + "<br>");
document.write("newcol:" + newcol + "<br>");
document.write("ans[0] + ans[1]:" + ans[0] + ans[1] + "<br>");
document.write("ans[1] + ans[0]:" + ans[1] + ans[0] + "<br>");
document.write("ans[1] + ans[1]:" + ans[1] + ans[1] + "<br>");
}
document.write("size:" + size + "<br>");
document.write("start:" + start + "<br>");
document.write("step:" + step + "<br>");
document.write("row:" + row + "<br>");
document.write("col:" + col + "<br>");
document.write("count:" + count + "<br>");
document.write("number:" + number + "<br>");
</script> |
