AIM: TO SWAP 2 NUMBERS WITHOUT USE OF TEMPORARY VARIABLE THEORY: C is a general-purpose, middle level, procedural computer programming language supporting structured programming, lexical variable scope, and recursion, with a static type system. C is an imperative procedural language. Let a and b be variables in which integral values are being inserted . tw numbers can be swapped without using a temporary variable by using arithmetic operations. Another alternative method is by use of logical operators. ALGORITHM: STEP 1: Start STEP 2:Print "Enter two numbers'" STEP 3: Input x,y STEP 4:Print “ Numbers x,y before swapping STEP 5: x x+y STEP 6: y<– x-y STEP 7: x x-y STEP 8: Print “ Numbers x,y after swapping " STEP 9: Stop
Regular expression to NFA to DFA conversion: Describes the process of taking a unique regular expression, converting that regular expression to an NFA, then converting the NFA into a DFA. Your regular expression must have at minimum two union, two concatenation, and two Kleene star operations. As followed, concatenations of single charaters can be condensed. Your regular expression cannot be a solved problem from any book. You should describe the regular expression with both processes to convert the regular expression to an NFA and the conversion of that NFA into a DFA.
Q3: Superheroes Supervillains are tired of Toronto condo rental prices, so they are leaving Toronto for Mississauga. Luckily, we have valiant superheroes that can deal with them. The superhero () has a name , an intelligence score , and a strength score .ni-th0 = gin[x] + s[x] Detective Zingaro has asked for your help. For each of the supervillains, tell him the name of the superhero that should deal with that supervillain. Note: A superhero can be assigned to multiple supervillains (or none at all). Note: whenever there are multiple superheroes that satisfy the given requirements for a supervillain, report the one whose name is lexicographically smallest (i.e. the one that’s the smallest according to Python’s ordering of strings). It’s guaranteed that superheroes have distinct names. Hint: Tuples of multiple elements may be helpful here. In python, you can compare two tuples and . If and are different, the result is the same as comparing and . If and are equal, the result is the same…
Python only* Use recursive function*. Define concentricCircles with 4 parameters Use def to define concentricCircles with 4 parameters here is the specification for concentricCircles function: It draws a series of concentric circles, where the first parameter specifies the radius of the outermost circle, and the second parameter specifies the number of circles to draw. When viewed as nested rings, all rings should have the same thickness. The third and fourth parameters specify an outer color and an other color, respectively. The outer color is used for the outermost circle, and then every other circle in to the center alternates between that color and the other color. We will test both how many circles are drawn as well as whether the correct circles are drawn in the correct order. Hint: Each function call frame only needs to draw a single circle. Note that you must use the turtleBeads drawDot function to draw each circle Do not use any kind of loop Within the definition of…

Problem 2 -- Recursive Palindrome (Grey + Scarlet) Write a recursive method, isPalindrome, which takes a String as a parameter, and returns true if the String is a palindrome. For the purposes of this method, you may assume Strings with a length of o or 1 are palindromes.
Recursive Power FunctionWrite a function that uses recursion to raise a number to a power. The function should accept two arguments: the number to be raised and the exponent. Assume that the exponent is a nonnegative integer. Demonstrate the function in a program. SAMPLE RUN #0: ./recursiveExponent Hide Invisibles Highlight: Show Highlighted Only 2^3=8↵ 2^4=16↵ 3^3=27↵ 6^3=216↵ 7^7=823543↵ 10^9=1000000000↵
3. Largest: a recursive function that computes the largest value for an integer array of positiveand negative values. For example, for the array below, the function largest should return 22,which is the largest value in the array. You can assume there are no more 20 integers in thearray. Think of how to formulate the recurrence relation in this problem yourself.
Create a recursive function that simulates the range function. For example: Enter the range (begin, end, increment) separated by spaces: 3 15 3 [3,6,9,12]
Recursive Sum! Write a recursive function rc_sum(n:int) -> int that returns the sum of the first n positive integers. The function should look very similar to the factorial function you have seen before. Your Answer: 1 # Put your answer here 2 Submit
3. Let A = {1, 2, 3, 4, 5} and B = {0, 3, 6}. Find а) AUB. с) А — В. b) ANB. d) В — А.
Recursive Copy Function Given a string str and number n, write a program that recursively appends a copy of string str n times and returns the resulting string. For example: RecuriveCopy("a", 10)//-> "aaaaaaaaaaa"RecursiveCopy("blah",5)//-> "blahblahblahblahblahblah" Please complete the following function. n is the number of copies to add to str: function RecursiveCopy(str, n) {// your code here} The problem must satisfy the following: You must use recursion. You should end up with n+1 copies of the str total in the output because you are appending additional str copies. Use string literal formatting for the output.
