In this problem, we will use our knowledge of maps and lists to build a spell-checking program. the class main contains the starter code for this problem; your task is to complete this program. you are provided with a file titled words. txt, which contains a list of valid english words, one per line. your program should take as input a line of space-separated words representing a sentence. (no punctuation or capitalization will be used; all characters will be either the space character or a lowercase english letter). you should then output a list of words in the input that are misspelled, each on their own line, followed by a newline. for example, if our input is: teh qwick braown foxx jumpps ovar teh laizy dogthen we should print: : (a) you may not use any of java’s built-in data structures except for arrays. (in particular, you should write your own implementation of hashset. i suggest calling this myhashset. additionally, if you want to use lists to handle collisions, you will need to write your own implementation of a linkedlist or ) your algorithm should run in approximately o(m+n) time, where m is the total number of words in the file words. txt and n is the number of words in the input sentence.
