 Need Help??
Dear all,
Suppose I have the following array and hash:
```my @arr = ('foo','bar','qux','foo1','bar1','qux1');

my \$hash = {
'4-5' => '0.750',
'0-4' => '0.167',
'0-2' => '0.600',
'2-3' => '0.200',
'2-4' => '0.300',
'0-3' => '0.300',
'2-5' => '0.400',
'1-2' => '0.550',
'1-5' => '0.273',
'3-4' => '0.300',
'1-4' => '0.182',
'0-1' => '0.917',
'3-5' => '0.400',
'0-5' => '0.250',
'1-3' => '0.300'
};

Now the key and value of \$hash represent the following:
```    'x-y' => 'VALUE'

x and y represent the index of the element in @arr
x and y are reversible

so for example:

'0-3' => '0.300', means that
'foo' and 'foo1' has value 0.300 OR
'foo1' and 'foo' has value 0.300
Now my question is, how can we sort decendingly @arr_sorted, such that for every index 'z' in @arr, the VALUE of its (z,y) <= (z,y+1)?

Members of @arr_sorted is exactly the same as @arr, only sorted according to the condition above. And yes, every 'z' has its corresponding @arr_sorted.

I'm not sure how to proceed from here:
```
foreach my \$z (0 .. (\$#arr-1)) {

my @arr_sorted = sort{???} @arr;

}

Updated.

Regards,
Edward
