Subtasks

• Subtask 1 (20 points): $-10\le A,B,C,D\le 10$.
• Subtask 2 (30 points): $-1000\le A,B,C,D\le 1000$.
• Subtask 3 (50 points): $-1000000000\le A,B,C,D\le 1000000000$.

Examples

Example 1

Input

2 3 2 6

Output

Valores aceitos

Explanation

The input gives 2, 3, 2, 6. 3>2: True; 6>2: True; 2+6>2+3: True; both C and D positive: True; A even: True. Therefore the required output is ['Valores aceitos'].

Example 2

Input

2 3 2 2

Output

Valores nao aceitos

Explanation

The input gives 2, 3, 2, 2. 3>2: True; 2>2: False; 2+2>2+3: False; both C and D positive: True; A even: True. Therefore the required output is ['Valores nao aceitos'].
