a = int(input())
b = int(input())
res = a*10+b
if res<b*10+a:
  res = b*10+a
print(res)

Bài 24:
- Xác định bài toán:
Input: a,b,c
Output: S là diện tích tam giác nếu a,b,c là 3 cạnh của 1 tam giác, “NONE” nếu a,b,c không là 3 cạnh của 1 tam giác
- Thuật toán:
B1: Đưa hàm sqrt ra + Nhập a,b,c
B2: Lấy m=a+b, n=b+c, p=c+a
B3: (1) Nếu (m>c) và (n>a) và (p>b) thì:
3A: Tìm p=(a+b+c)/2
3B: Tìm s= sqrt(p.(p-a).(p-b).(p-c)) (Công thức Hê rông)
(2) Nếu m,n,p không thỏa mãn (ELSE) thì ghi “NONE”
B4: Đưa ra kết quả cho từng trường hợp
