代码编写不会，一道数学题

#include<stdio.h>
int main()
{
    int x,y;
    scanf("%d", &x);
    if(x<0){
        y=-x;
    }
    else if(x<5){
        y=2*x+1;
    }
    else{
        y=5*x-1;
    }
    printf("%d", y);
    return 0;
}

x=int(input("输入："))
if x<0:
    y=-x
elif x>=0and x<5:
    y=2*x+1
else:
    y=5*x-1
print(y)
