Hello, i need some help i need to dynamically delete items from some arrays

My arrays are like this:

 

[
[1,2,3],[1,2,332],[1,22,113],[1,223,323]

Second: I need to delete some items of my array,  example: like the 3 first items

[
[1,223,323]
]

Hi @madmvx 

Thank you for posting.

You can use the ‘length’ and ‘skip’ function to get the array you want.

Please refer to the screenshot as below:

You can use ‘Length’ function to return the number of items in the array.

Expression:length(variables('myArray'))

Than you can use ‘skip’ function to remove items from the front of a collection, and return all the other items.

Expression:skip(variables('myArray'),add(outputs('Compose_2'),-1))

After the flow runs,you will get the array as below:
