Analyze an input row of 4 symbols and an output row that has been rearranged by an operator. Deduce the correct numeric operator (e.g., 3241) that describes how the symbols shifted position.
Compare the input sequence of four symbols with the target output sequence.
Each 4-digit operator indicates which input position moves to each output slot (e.g., '3241' moves the 3rd symbol to slot 1, 2nd to slot 2, 4th to slot 3, and 1st to slot 4).
On advanced levels, two stacked operators transform the symbols sequentially.
Quickly eliminate wrong operators by checking just one unique symbol position first.
