Class Name: Shaky
Method Name: isShaky
Parameters: int
Returns: int
TopCoder has made up a term to describe a certain type of number. We call it a
"shaky" number. You can determine if a number is shaky according to the
following rules:
(1) starting from the left-most digit and moving right, a pattern must be
followed of "greater than", "less than", "greater than", "less than", etc. For
example, 465768 is considered shaky because
6 is greater than 4,
5 is less than 6
7 is greater then 5
6 is less than 7
8 is greater than 6
(2) any single digit number IS considered shaky.
(3) The first comparison may be "greater than" or "less than", and alternate
after that. It does not necessarily need to end with a "greater than" or "less
than".
Implement a class Shaky that contains a method isShaky. The method takes an int
as a parameter and returns 1 if the int is shaky and 0 otherwise.
Here is the method signature:
public: int isShaky(int in);
in is positive and less than 1000000.
EXAMPLES:
5252 - should return 1
2525 - should return 1
25 - should return 1
52 - should return 1
8 - should return 1
33 - should return 0
521 - should return 0
23234 - should return 0
