func pageCount(n int32, p int32) int32 {
    // Write your code here
    if n%2==1{
        n=n-1
    }
    if p%2==1{
        p=p-1
    }
    if n==p{
        return 0
    }
    left :=false
    begin:=int32(0)
    if (n-p)<p{
        left = true
        begin=n
    }
    countpage:=int32(0)
    if left==false{
        for begin<p{
            begin+=2
            countpage++
            fmt.Println(begin)
        }
    }else if left==true{
        for begin>p{
            begin-=2
            countpage++
        }
    }


    return countpage
    
}
