Your professor wants you to find which value
A,B,C or D changes in two different indexes.
e.g. if he gives 11 and 10,
- for 11: A=1; B=0; C=1; D=1;
- for 10: A=1; B=0: C=1; D=0;
so you should print D.
Question:
- You are given 2 numbers. You will give the result
only if they are in same row or column, you can't
pick 0 and 5 for example.
- Also the numbers must be adjacent or border
numbers, for ex. 4 and 6; 0 and 8. You can't
have 0 and 12 or 0 and 3.
- The indexes 0-15 are as shown in figure.
Question:
Write a program that gets two numbers which are
between 0 and 15. Then, your program finds which
letter A,B,C or D is different or changes in
those indexes.
Input specification
You will be two different numbers between 0 and 15.
Output specification
Show one letter (capital): which value (0 or 1)
is different or changes in those indexes.
If any of the two restrictions are violated
print "ERROR"
