You are tasked to allow the user to enter a string consisting of zero or more Alphanumeric Words. Your program should replace Alphanumeric Words that are valid hexadecimal values with their decimal ere: ttnews sftpedia More formally, write MIPS assembly code in MARS to allow the user to enter a line of text.

Alphanumeric Words, if present, consist of only Uppercase Letters (A,B,C, , Z} and/or Numeric Digits {0, 1,2, , 9).
