Final answer:
Byte pair encoding (BPE) is a data encoding technique that can be used to shorten the length of strings by replacing pairs of characters. It is possible to use BPE to shorten the length of all the given strings.
Step-by-step explanation:
Byte pair encoding (BPE) is a data encoding technique used in computer science and natural language processing. It is a form of compression that replaces pairs of characters with a single character that does not appear in the string. The algorithm creates a list of character pairs and their corresponding replacement characters.Based on the given examples, BPE can be used to shorten the length of the strings 'BANANA', 'LEVEL_UP', 'MEET_ME_LATER', and 'NEITHER_HERE_NOR_THERE'. In each case, there are pairs of characters that appear more than once and can be replaced. For example, in 'BANANA', the pair 'NA' appears twice and can be replaced with a single character (e.g., '%').Therefore, it is possible to use byte pair encoding to shorten the length of all the given strings.
