Example 1:
Input
2
4 12
2375 7682 2325 2352
250 500 350 200
3 8
2222 2223 2224
200 300 400
Output:
600
300
Method:

- Check the Date
- Update the Sum of Penalties of Even Car Numbers and Update the Sum of Odd Car Numbers.

- Else,Print Sum of Penalties of Odd Car Numbers

###### Python Code

    t = int(input())
    for c in range(t):
        n,d=input().split()
        car_num=[int(x) for x in input().split( )]
        fine =[int(y) for y in input().split( )]
        amount=0
        if (int(d)%2==0):
            for i in range(len(car_num)):
                if (car_num[i]%2!=0):
                    amount+=fine[i]

        else:
            for i in range(len(car_num)):
                if(car_num[i]%2==0):
                    amount+=fine[i]
        print(amount)
