A very known application in natural language processing is to extract information from a given text. In this lab, you will be able to extract some emotions (Sad and Happy) from a given string and calculate the score of each emotion. You will be given below the words that express sadness, anger, and happiness. For each word, you will be given weight as well, so that when you are calculating for example the score for sadness in the text (string), you can use this formula:

1- Given an input consisting of one or more sets of strings, followed by a final line containing only the value 0. Each set starts with a line containing an integer, k, which is the number of strings in the set, followed by k strings, one per line. For example, if your input is: Input = { "7", "Bo", "Jean", "Marybeth", "Kevin", "Claude", "William", "Pat", "6", "Jim", "Ben", "Annabelle", "Zoe", "Joey", "Frederick", "5", "John", "Billy", "Fran", "Stant", "Cece", "2", "Jones", "Bibi", "0" } Your output should look like that: 2- Given the sorted input from question 1, write a new code such that the shorter strings go on the top and bottom and the longer strings sit in the middle. In other words, each pair of names belongs on opposite ends of the list, and the first name in the pair is always in the top part of the list. For example, in Set 1 below, Bob and Joe are the first pair, Jean and Kevin the second pair, etc. Your output should look like the sample below.…
Given a reference string followed by four (4) more strings, create a program that determines whether those 4 strings are anagrams of the reference string. The output should be a list of boolean values that show if those strings are anagrams (respectively). For our purposes, there’s no need to check if a string is a valid word or not (i.e. it’s in the English dictionary). NOTE: Do not use sorted()
