题解：

func PredictTheWinner(nums []int) bool {return total(nums, 0, len(nums) - 1, 1) >= 0
}func total(nums []int, start, end int, turn int) int {if start == end {return nums[start] * turn}scoreStart := nums[start] * turn + total(nums, start + 1, end, -turn)scoreEnd := nums[end] * turn + total(nums, start, end - 1, -turn)return max(scoreStart * turn, scoreEnd * turn) * turn
}func max(x, y int) int {if x > y {return x}return y
}
