Description
The input is a four-digit positive integer x that consists of digits 1-9 except 0. Let y be the number with the first two digits and the rest of x swapped. For example, if x is 9527, then y is 2795. Now, calculate z, which is the square of y, and encode z by the following mapping:
1->’A’, 2->’B’, 3->’C’, …, 9->’I’, 0->’J’
You should pad 0 on the left of z to make z an eight-digit number before encoding.
That is, since y is 2795 and its square z is 7812025, the padded version of z is 07812025, and so your answer should be JGHABJBE.
Input
A four-digit positive integer consisting of 1-9 except 0.
Output
The encoded z. Note that you do not need to print ‘ ’ at the end of the output.
