Time Complexity

In computer science, the computational complexity that is measured in terms of time is referred to as time complexity that defines how long it takes a computer to execute an algorithm. An algorithm's time complexity is measured by the the amount of time required to execute each statement of code in the algorithm. If a statement is set to execute repetitively, the number of times it will be N multiplied by the time it takes to run that function each time is equal .

A class may occasionally be dependent upon itself. In other words, an object of one class engages in communication with an object of the same class. To do this, a method of the class can take an object of the same class as a parameter.An illustration of this scenario is the concat method of the String class. One String object calls the method, while another String object is supplied as an argument. Here's an illustration:str2 = str1.concat;The String object (str1) that executes the method adds its characters to the String (str2) that was supplied as a parameter. As a result, a fresh String object is produced and saved as str3. Write Java code to put the circumstances given into effect.

Write a C-program, which reads five English words in thefollowing order, an article (A/An/The), a noun, a verb (in simplepresent or past tense), an article, and a noun. For any of these words,if you provide a digit as a string, it will consider the word as an emptystring. The program forms an English sentence in another string bytaking care of blank spaces in between and appending the punctuationsymbol ‘full stop’ (.) at the end. While converting, it would take careof converting any upper case alphabet to a lower case alphabet if it isnot the first word of the sentence. Similarly, it would convert a lowercase alphabet of the first alphabet of the first word in the sentence toan upper case alphabet. Finally, it prints the sentence.For example:(i) Input: “the”, “Girl”, “reads”, “a”, “Book”.Output: “The girl reads a book.”(ii) Input: “5”, “they”, “Went”, “2”, “Home”.Output: “They went home.”
IN JAVA Write a function that takes in user input as a string. For all characters which are numeric, double its value and, if it is two digits, then replace it with the sum of its digits (e.g., 6 → 12 → 3 whereas 3 → 6). For all characters which are in uppercase, replace it with lowercase. For all characters which are in lowercase, replace it with uppercase (e.g., m → M and N → n). The program should keep asking the user to enter strings until they either enter ‘q’ or ‘Q’.
Given a String check to see if the parenthesis contained in the String are balanced. Balanced parenthesis means for every open ( parenthesis there is a corresponding closing ) parenthesis and vice versa. Return the String "balanced" if they are balanced and "unbalanced" if they are not balanced. public class ParenthesisBalance{public static String solution(String s){// ↓↓↓↓ your code goes here ↓↓↓↓return null;}}
Write a subroutine that takes a simple sentence in noun-verb-object form and parses the sentence into its different parts.

Suppose you have a list of key/value pairs (i.e., a nested list where each element of the list is a (key value)pair. For example, the list might look like this: '((France Paris) (France Nice) (Spain Madrid) (Poland Krakow) (Poland Warsaw)) (Notice that the keys need not be unique for this problem.) Write a function named first-occurrence in Scheme that takes a key and a list then returns the value of the first item on the list with a matching key. Return '() if none of items on the list has a matching key. You must use either fold or reduce to do the vast majority of the work. You may use the built-in foldmethod by adding the line (require 'list-lib), or you can use your own implementation. The built-in fold function has parameters in this order: action partial-result lst. You may assume that the list contains an element with the key to be updated. For example, (first-occurrence 'Germany '((France Paris) (Germany Bonn) (Germany Berlin))) should return 'Bonn (first-occurrence 'Poland…
