Mr. Broken fell in love in Japan but it was impossible to be with her after she went back to America.
Therefore, Mr. Broken wants to separate all couples and mess everything up.
There's a 4-digit number consisting of 1~9 except 0.
Mr. Broken will separate the first two digits from the last two digits, and then multiply them together.
Can you compute the result after Mr. Broken mess everything up?
For example, if the number is 6784, the first and last two digits are 67 and 84, then the answer is 67*84=5628.
