Problem description

Validate Stack Sequences. Simulate push/pop. For Validate Stack Sequences, focus on the exact input variables, return only the requested value, and preserve the required time complexity for the intended pattern.

Examples

Input {"pushed": [1, 2, 3, 4, 5], "popped": [4, 5, 3, 2, 1]}; Output true. Input {"pushed": [-6, 12, 0, 17, 4, 19], "popped": [10, -1, 0, 0, 7, 19]}; Output false. Input {"pushed": [1, -8, -10], "popped": [-3, 8, 5, 7, 9]}; Output false

Constraints

1 ≤ n ≤ 10^5
