Sum of two squares def sum_of_two_squares(n): Some positive integers can be expressed as a sum of two squares of some positive integers greater than zero. For example, 74 = 49 + 25 = 72 + 52. This function should find and return a tuple of two positive integers whose squares together add up to n, or return None if the parameter n cannot be broken into a sum of two squares.To facilitate the automated testing, the returned tuple must present the larger of its two numbers first. Furthermore, if some integer can be broken down to a sum of squares in several ways, return the breakdown that maximizes the larger number. For example, the number 85 allows two such representations 72 + 62 and 92 + 22 , of which this function must return (9, 2).The technique of two approaching indices that start from the beginning and end of a sequence, respectively, and approach each other until they meet somewhere, used in the function two_summers in one of our class examples, is directly applicable to this…
Magic Number Programming:
Magic program ask user to enter three integers by the user, the three integers represent left bound,
right bound and arbitrary digit 'm', where left bound is less than right bound. Program should print all
magic numbers in the given range that doesn't contain digit 'm'. The number is magic if its every digit is
larger than the sum of digits which are on the right side of that digit. For example, 94210 is magic
number because 1 > 0, 2 > 1+0, 4>2+1+0, and 9 > 4+2+1+0.
Write a complete C program that Call only One Function (magic_numbers) that will print all magic
numbers excluding a given digit 'm' that also entered by user ?
Input Sample :
Enter Left bound: 740
Enter Right bound:850
Enter digit to exclude it:2
Output sample:
Magic Numbers in Range Left=740, Right=850 with exclude digit m= 2 are:
740 741 750 751 760 810 830 831 840 841 843 850
Your function prototype is like this:
void magic_numbers(int left, int right, int digit) ;
Cyclops numbersdef is_cyclops(n):A nonnegative integer is said to be a cyclops number if it consists of an odd number of digits so that the middle (more poetically, the “eye”) digit is a zero, and all other digits of that number are nonzero. This function should determine whether its parameter integer n is a cyclops number, and return either True or False accordingly

The last digit of a credit card number is the check digit, which protects against transcription errors such as an error in a single digit or switching two digits. The following method is used to verify actual credit card numbers but, for simplicity, we will describe it for numbers with 8 digits instead of 16:• Starting from the rightmost digit, form the sum of every other digit. For example, if thecredit card number is 4358 9795, then you form the sum 5 + 7 + 8 + 3 = 23.• Double each of the digits that were not included in the preceding step. Add all digits ofthe resulting numbers. For example, with the number given above, doubling the digits,starting with the next-to-last one, yields 18 18 10 8.

This function should compute and return the list of all numbers that the positive integer n can be converted to by treating it as a string and replacing some substring m of its digits with the new substring of either 2*m or m/2, the latter substitution allowed only when m is even so that dividing it by two produces an integer. This function should return the list of numbers that can be produced from n in a single step. To keep the results more manageable, we also impose an additional constraint that the number of digits in the chosen substring m must be between mink and maxk, inclusive. The returned list must contain the numbers in ascending sorted order.arrow_forwardLaunch Meeting - Zoc X S Launch Meeting Zoc X Is Everyone Really Equ x E Reading Response 6 OCh7: Oppression & Se x SThank you for downlc X s.ucsc.edu/courses/46018/assignments/294537 2. are_anagrams This function takes two strings and returns True if they are anagrams of one another, which is to say that they contain the same letters, possibly rearranged, ignoring spaces and case.
