Question Answered step-by-step One way to mask a message, M , using a version of steganography, is… One way to mask a message, M , using a version of steganography, is to insert random characters into M at pseudorandom locations so as to expand M into a larger string, C. For instance, the message, ILOVEMOM, could be expanded into AMIJLONDPVGEMRPIOM. It is an example of hiding the string, M , in plain sight, since the characters in M and C are not encrypted. As long as someone knows where the random characters where inserted, he or she can recover M from C. The challenge for law enforcement, therefore, is to prove when someone is using this technique, that is, to determine whether a string C contains a message M in this way. Thus, describe an O(n)- time method for detecting if a string, M , is a subsequence of a string, C, of length n.
