Problem: Write a program to play a variety of BlackJack. In general, given two numbers, a and b, return their sum.
If the sum is greater than 21, return 0, unless one of the numbers is 11. In such a case, the 11 should be 'converted' to a 1 to prevent the sum from being exceeded.
For example, given a 11 and 13 as input, the 11 should be 'converted' into a 1 so the total sum will be 14.
Input: Input contains 2 space separated integers, a and b
Output: Output will be in general sum of a and b, if sum exceed 21, return 0, unless one of the numbers is 11. In such a case, the 11 should be 'converted' to a 1 to prevent the sum from being exceeded.
For example, given a 11 and 13 as input, the 11 should be 'converted' into a 1 so the total sum will be 14.
Constraints: 0<=a<50
0<=b<50
Sample Input: 11 13
Sample Output:
14
a, b = map(int, input().split())
s = a + b
if s > 21 and 11 in (a, b):
s -= 10
print(s if s < 22 else 0)
