- Specify and implement an iterator method called sortedElements for IntSet. The iterator method sortedElements returns an iterator that will produce each element of the intset in ascending order. The intset cannot be mutated when the iterator is in use. Be sure to specify the iterator method before implementation. Do not forget to give the rep invariant and abstraction function for your implementation. Note: IntSet.java has been provided. You can directly add in the code the specification, the implementation of the iterator method sortedElements, and the inner iterator class. There is a segment of simple testing code for sortedElements in main() close to the end in the provided IntSet.java. The program will not compile until you have properly implemented sortedElements. find the provided code below: https://drive.google.com/open?id=1hANO8kVigGXwFLLJDJQLE5joM1BBeCCnThe QObject class is a simplified application of the composite pattern because it plays the role of all the classes in the pattern. True or falseThe "dynamic array" data structure is used as the basis of Java's ArrayList library class. Describe this data structure and explain how it achieves (amortized) constant-time adding of elements, while also giving constant-time random access of elements. As part of your answer, make sure to explain what "amortized" means for the data structure.
- Write the code in python to define the function has_adjacent_repeats(mystr), which takes a string parameter and returns a boolean result. - If mystr has at least one instance of adjacent characters being equal, return True - Otherwise, return False Hint: You can iterate over the positive indices i for characters in mystr: 1, 2, 3, ...., len(mystr)-1 with a for loop. For each i, if the character at index i matches the character at index i - 1, return True. Otherwise, if no doubled character is found in the entire string, return False. For example: Test Result if not (has_adjacent_repeats("NOODLES") is True): print("error") if not (has_adjacent_repeats("Bananas") is False): print("shwoopsie") if not (has_adjacent_repeats("Hanoverr") is True): print("error")Find on the internet (or use a camera to take) three different types of images: an indoor scene, outdoor scenery, and a close-up scene of a single object. Write python code to implement an adaptive thresholding scheme to segment the images as best as you can and write a brief summary.Recursion and loops. Provide both recurrent and loop based implementation of the function count( e, L ) that returns the number of es in L, where L is a list. Also consider cases when L is an empty list. Create test cases and run driver, show how function runs in spyder (py file) or ipynb file. Submit code as a py or html or pdf files with screenshots of the runs.
- Allow student to insert one arbitrary string. Save the letters of the string into a list. Design and perform the following tasks and display your results: • Summarizing letters in a string. Write a function that receives a string and returns a list of tuples containing the unique letters and their frequencies in the string. Test your function and display each letter with its frequency. Your function should ignore case sensitivity (that is, 'a' and 'A' are the same) and ignore spaces and punctuation. When done, write a statement that says whether the string has all the letters of the alphabet. • Present descriptive statistics and graphs about the string data. • Sorting letters in different order and removing duplicates • Write a code that produces anagrams of a given string. An anagram of a string is another string formed by rearranging the letters in the first. program must accept inputs from a user, performs an operation using a userdefined function which will accept parameters and…Split blood pressure into systolic and diastolic blood pressure with integer as data type readings and remove the original column. Examine the data and look for predictor columns that are indicator variables, 0 or 1. Convert the data type to Boolean. Using code prepare lists of predictor column names for each data type. Make sure all the predictor columns are included in one and only one list. Print the length of the list of each data type and the sum of the lengths and verify that all predictor variables are accounted for in the lists. Use f-string to align the numbers properly.Q1. Implement regular expression matching with support for '.' and '*'. '.' Matches any single character.'*' Matches zero or more of the preceding element. The matching should cover the entire input string (not partial). The function prototype should be:bool is_match(const char *s, const char *p) Some examples:is_match("aa","a") → falseis_match("aa","aa") → trueis_match("aaa","aa") → falseis_match("aa", "a*") → trueis_match("aa", ".*") → trueis_match("ab", ".*") → trueis_match("aab", "c*a*b") → true""" def is_match(str_a, str_b): """Finds if `str_a` matches `str_b` Keyword arguments: str_a -- string str_b -- string """ len_a, len_b = len(str_a) + 1, len(str_b) + 1 matches = [[False] * len_b for _ in range(len_a)] # Match empty string with empty pattern matches[0][0] = True # Match empty string with .* for i, element in enumerate(str_b[1:], 2): matches[0][i] = matches[0][i - 2] and element == '*' for i, char_a in enumerate(str_a, 1):…
- established a method for keeping track of parking lot lease agreements. Now that we are more comfortable with ordered structures, we return to that example and add a new element—an alphabetical list of contracts. As customers rent parking spaces from the parking office, contracts are added to a common list of relationships between renter names and lot allocations. We are now changing that structure to reflect a more efficient way of storing this data—an ordered list of related associations.in this assignment i have to remove vowels from a string using a linked list. the linked list and link code is from a textbook and cannot be changed if the code alters the data structure. for some reason when i implement this code it gives me a logical error where the program only removes all instances of the first vowel in a string instead of moving through all vowels of the string and removing each one with all instances. i would appreciate if you could tell me the problem and solution in words and not in code.
