How to operate this one-degree array?

[happybird]

i have a one-degree array like the following:

0 0 0 2 3 4 5
how to move 2,3,4,5 to the first four position to form the result like this:
2 3 4 5 0 0 0

thanks!

Try the attached vi. If you can't read the file then here is a description

1. Reverse the array and get the array length
2. Search the reversed array for the first zero
3. Subtract this number from the array length
4. Use this number to split the original array
5. Take the two new array and concatenate them in reverse order.

If you always have 3 leading zeroes, just use "rotate array" with n = -3.

If you have a variable amount of leading zeroes and want to programmatically determine how much to rotate to get the first nonzero number at the beginning, use something like the simple code attached.

Randall, You are making the assumption that ALL elements after the first nonzero element are always nonzero. For example an input of 0,0,0,2,3,0,5 to your code would yield 5,0,0,0,2,3,0 which is probably not as intended. My code results in 2,3,0,5,0,0,0 for this case, which seems more reasonable.

Why not use the 'Delete From Array' / 'Insert into Array' functions of LabVIEW. Depending on your application, it may be a little more robust.

Take a look at this.

I am assuming the all the zeros will be in front because since all of the number were in ascending order, the array looked like it was sorted to me.
