题解：

type MinStack struct {stack []intminStack []int
}func Constructor() MinStack {return MinStack{stack: []int{},minStack: []int{math.MaxInt64},}
}func (this *MinStack) Push(x int)  {this.stack = append(this.stack, x)top := this.minStack[len(this.minStack)-1]this.minStack = append(this.minStack, min(x, top))
}func (this *MinStack) Pop()  {this.stack = this.stack[:len(this.stack)-1]this.minStack = this.minStack[:len(this.minStack)-1]
}func (this *MinStack) Top() int {return this.stack[len(this.stack)-1]
}func (this *MinStack) GetMin() int {return this.minStack[len(this.minStack)-1]
}func min(x, y int) int {if x < y {return x}return y
}
