Given a set of text files containing synonyms for different words, write a program to output the synonyms for a specific word. Each text file contains synonyms for the word specified in the file's name, and each row within the file lists the word's synonyms that begin with the same letter, separated by a space. The program should read a word and a letter from the user and open the text file associated with the input word. The program then should output all the synonyms that begin with the input letter, one synonym per line. If no synonyms that begin with the input letter are found, the program should output a message indicating so. Ex: If the input of the program is: educate c the program opens the file educate.txt, which contains: brainwash brief civilize coach cultivate develop discipline drill edify enlighten exercise explain foster improve indoctrinate inform instruct mature nurture rear school train tutor then the program outputs: civilize coach cultivate Ex: If the input of the program is: educate a then the program outputs: No synonyms for educate begin with a
