2 posts in this topic

I ned to sort an array. Heres what i mean

the fist dimension is infinite and the last array needs to never change

1st array:

$a[1][1] = 0xFFFFFF

$a[2][1] = 0xEEEEEE

$a[3][1] = 0xDDDDDD

$a[4][1] = 0xCCCCCC

$a[5][0] = 4

$a[5][1] = ""

2nd array:

$a[1][1] = 0xEEEEEE

$a[2][1] = 0xFFFFFF

$a[3][1] = 0xDDDDDD

$a[4][0] = 3

$a[4][1] = ""

2nd array after sort:

$a[1][1] = 0xFFFFFF

$a[2][1] = 0xEEEEEE

$a[3][1] = 0xDDDDDD

$a[4][0] = 3

$a[4][1] = ""

Please help me I am stumped :)

How did the counts wind up in the last row vice the first ([0][0])? That's very non-standard.

At any rate, this only takes two For/Next loops, one nested inside the other. Loop through the first array, and on each value loop through the entire second array, copying matches to a temporary array declared the same size as the second. On each match, you will be deleting that row from the second array, which means you need to loop with "Step -1" through it. After all the matches have been copied and removed, the remaining rows can be copied, including the last (count).

Give it a try. If you get stuck, post what you tried and you'll get plenty of help.
