Arguments
- array: Input array to rotate, must be dynamic array.
- rotate_count: Integer specifying the number of positions that array elements will be rotated to the left. If the value is negative, the elements will be rotated to the right.
Returns
Dynamic array containing the same amount of the elements as in original array, where each element was rotated according to rotate_count.

Examples
-
Rotating to the left by two positions:
print arr=dynamic([1,2,3,4,5]) | extend arr_rotated=array_rotate_left(arr,2)
Results
| arr | arr_rotated |
|---|---|
| [1,2,3,4,5] | [3,4,5,1,2] |
-
Rotating to the right by two positions by using negative rotate_count value:
print arr=dynamic([1,2,3,4,5]) | extend arr_rotated=array_rotate_left(arr, -2)
Results
| arr | arr_rotated |
|---|---|
| [1,2,3,4,5] | [4,5,1,2,3] |
