Write a function that takes three parameters: list of symbols $($as characters$),$ list of repetitions $($as positive integers$),$ and a boolean. Note that the lists can be of any length but lengths of these lists will always be the same. Your function returns a string containing characters from the symbols list repeated the corresponding number of times if the boolean parameter is True, and reversed otherwise. If both lists are empty, return an empty string. For example, Input Output Reason $[\text{'}-\text{'},\text{'}+\text{'}],[4,5],$ True $----+++++-$ is repeated $4$ times, $+$ is repeated $5$ times and everything is put together. def fourth$\_$pattern$($symbols$,$ repeats, switch$)$: $""">>>$ fourth$\_$pattern$([\text{'}-\text{'},\text{'}+\text{'}],[4,5],$ True$)\text{'}----+++++\text{'}>>>$ fourth$\_$pattern$([\text{'}-\text{'},\text{'}+\text{'}],[4,5],$ False$)\text{'}+++++----\text{'}"""$
