Comparing elements of array with previous ones and insert index of elements where v[i+1]

Hi,

i'm new to Labview. I'd like to get some helps to solve this kind of problem. I've got an array of integer in input and i must compare every element with previous one. If the element in i-th position is less than previous(i-1 th) then i must insert index of this element in another array in output, else if the element in i-th position is greather than previous(i-1 th) then i must insert zero in output array.

Example

Array in input=[1,36,2,3,43,6,8,1]

Array in output=[0,2,0,0,5,0,7]

Any helps would be kindly appreciated. Thank you so much.
