As an example, "xd" is unique but "xxd" is not.If there are two equalength unique substrings within , return the onethat starts first (i.e., begins at a smaller index).Note on grading for this question:You've already implemented a function that can generate all thesubstrings of a given string in lab 5. You can use that logic to helphere, but it will be quite slow.For this question, PERFORMANCE WILL MATTER, and we will run long tests withup to 10,000,000 characters as an input. To get full credit, an input of10,000,000 characters should return the correct answer within 60 seconds(the instructor solution takes about 2).Helpful tips:In order to get your function to run fast, consider using a dictionary tostore the indexes of previously seen characters, from there, you canfollow a set of rules based on each new character you see to determinethe length of the longest unique substring seen so far.>>> Longest_unique_substring ('aab')'ab'pass

You can assume that the two input strings contain only letters and spaces. Sample calls should look like this: >>> are_anagrams ("bimmy is my friend", "My Bird Fey Minims") True >>> are_anagrams ("bimmy is my friend", "hello everyone") False >>> are_anagrams ("internet anagram server", "I rearrangement servant") True >>> are_anagrams ("internet anagram server", "internet anagram server") True 3. find_movies_by_director 4:11 PM This function takes a list of tuples (representing movies) and a string (representing a name of a director) and returns a 65°F Sunny 11/2/2021 e search
Write in C Language Frequent Letter Your Facebook account has just been hacked and you want to change its password. To create a strongpassword, Facebook just recommended you two strings S and T, each contains N lowercase English letters. You want to choose a password containing N lowercase English letters such that the i th character is either the i th character of S or the i th character of T. For example, if S = icyz and T = ixpc, then there are 8 different passwords that you can choose: icyz, icyc, icpz, icpc, ixyz, ixyc, ixpz, ixpc. The strength of your password is defined as the number of occurences of the most frequent letter. For example, the strength of icyz is 1 and the strength icpc is 2. You are wondering what is the strength of the strongest password that you can choose.
get_nth_word_from_string(s, n): This function takes a string s and a non-negative integer n as input. The string s may contain substrings of text separated by commas. The function should return the n’th comma-separated substring. We will start counting at 0, so if n=0, then the first substring should be returned (i.e., everything before the first comma, if there is such a comma); if n=1, then the second substring should be returned (i.e., everything between the first comma and second comma, if there is such a comma); and so on. If there is no n’th substring in s, then the empty string should be returned. Note: You may use the string count method in this function. Note: If a space follows a comma, do not include the space as part of the substring to be returned.

String Pair // Problem Description // One person hands over the list of digits to Mr. String, But Mr. String understands only strings. Within strings also he understands only vowels. Mr. String needs your help to find the total number of pairs which add up to a certain digit D. // The rules to calculate digit D are as follow // Take all digits and convert them into their textual representation // Next, sum up the number of vowels i.e. {a, e, i, o, u} from all textual representation // This sum is digit D // Now, once digit D is known find out all unordered pairs of numbers in input whose sum is equal to D. Refer example section for better understanding. // Constraints // 1 <= N <= 100 // 1 <= value of each element in second line of input <= 100 // Number 100, if and when it appears in input should be converted to textual representation as hundred and not as one hundred. Hence number…
def substring_with_largest_sum(string: str) -> str:"""Given a string <string>, return the substring with the largest sum (ascalculated by sum_string()) that exists within <string>. If there aremultiple substrings with equally large sums, return the first one thatoccurs. The substring could just be the whole string itself, or it couldbe empty. To calculate the sum of the substring, please use the function sum_string()which you have implemented above as a helper. For example, given the string "321", there are 7 possible substrings:"", "3", "2", "1", "32", "21", "321". For each one of them, their sum canbe calculated as per the sum_string() function which you have alreadyimplemented. By using your understanding of loops, implement this functionto return the substring with the largest sum by checking all of thesubstrings of the input string. So, "32" evaluates to 1, "21" alsoevaluates to 1, "321" evaluates to 2, resulting in "3" being the largestpossible substring as it…
get_nth_comma_in_string(s, n): This function takes a string s and a non-negative integer n as input. It returns the index of the n’th comma in the string s. We will start counting at 0, so if n=0, then the index of the first comma should be returned; if n=1, then the index of the second comma should be returned, and so on. If there is no n’th comma in s, then -1 should be returned. Note: You may use the string find method in this function.
What input or parameter value impacts the number of times the recursive function will be called. • Give three specific examples of input/parameter values and, for each, state the number of times the recursive function will be called. • Devise a formula with respect to n that describes the number of times the recursive function will be called, where n is either the value passed or some property of the value passed (e.g. n might be the length of a string of the size of an array).
• get_tokens_from_equation(line): Takes one string as input that contains any combination of digits from 0-9 and the following mathematical symbols: + - x / = ^ (O The string does not have to correspond to a valid mathematical equation. For example, '4-3=0' and '4xx5=(8' could be valid inputs to this function. The function will translate the string into a list of tokens. A token is a single non-negative number (of any length) or a single mathematical symbol. Numbers should be added to the list as integers, and symbols as strings. The tokens in the list should be in the same order as the numbers/symbols appear in the string. For example, given the string '52-2=50', the function should return the list [52, '-', 50]. >>> get_tokens_from_equation('4=3') [4, '=', 3] >>> get_tokens_from_equation('6-5=15^4/2') [6, '-', 5, '=', 15, '^', 4, '/', 2] >>> get_tokens_from_equation('288/24x6=18x13x8') [288, '/', 24, 'x', 6, '=', 18, 'x', 13, 'x', 8]
