EBCDIC （多校联合赛第九场E题）

E. EBCDICTime Limit: 2000msCase Time Limit: 2000msMemory Limit: 102400KB64-bit integer IO format: %I64d Java class name: MainSubmit Status PID: 33810Font Size: + -A mad scientist found an ancient message from an obsolete IBN System/360 mainframe. He believes that this message contains some very important secret about the Stein's Windows Project. The IBN System/360 mainframe uses Extended Binary Coded Decimal Interchange Code (EBCDIC). But his Artificial Intelligence Personal Computer (AIPC) only supports American Standard Code for Information Interchange (ASCII). To read the message, the mad scientist ask you, his assistant, to convert it from EBCDIC to ASCII.
Here is the EBCDIC table.

Here is the ASCII table.

InputThe input of this problem is a line of uppercase hexadecimal string of even length. Every two hexadecimal digits stands for a character in EBCDIC, for example, "88" stands for 'h'.

OutputConvert the input from EBCDIC to ASCII, and output it in the same format as the input.

Sample Input

C59340D7A2A840C3969587999696

Sample Output

456C2050737920436F6E67726F6F
