Kevin wants to conduct a Boolean search on two different topics. Which Boolean operator should Kevin use to get the right search results?
Correct answer will be upvoted else downvoted. Computer science. example of a chainword is the accompanying triple: a line of m lowercase Latin letters; the main clue: an arrangement of fragments with the end goal that the letters that compare to each portion spell a word from the word reference; the subsequent clue: one more succession of portions with the end goal that the letters that relate to each section spell a word from the word reference. Note that the successions of portions don't really need to be unmistakable. Two occasions of chainwords are considered unique on the off chance that they have various strings, diverse first clues or distinctive second clues. Count the number of various examples of chainwords. Since the number may be really huge, output it modulo 998244353. Input The primary line contains two integers n and m (1≤n≤8, 1≤m≤109) — the number of words in the word reference and the number of letter cells. Every one of the following n…
