Frosh commencing their studies at Waterloo have diverse interests, as evidenced by their desire to take various combinations of courses from among those available. University administrators are uncomfortable with this situation, and therefore wish to offer a conformity prize to frosh who choose one of the most popular combinations of courses. How many frosh will win the prize? Input The input begins with an integer 1 ≤ n ≤ 10 000, the number of frosh. For each frosh, a line follows containing the course numbers of five distinct courses selected by the frosh. Each course number is an integer between 100 and 499. Output The popularity of a combination is the number of frosh selecting exactly the same combination of courses. A combination of courses is considered most popular if no other combination has higher popularity. Output a single line giving the total number of students taking some combination of courses that is most popular. Sample Input 1 Sample Output 1 3 100 101 102 103 488 100 200 300 101 102 103 102 101 488 100 Sample Input 2 3 200 202 204 206 208 123 234 345 456 321 100 200 300 400 444 2 Sample Output 2 3

Python Algorithm Question (similar to celebrity Python problem). Having trouble implementing the algorithm. Here's the question: Let’s say you’re going to invite some people to a party. You’re considering n friends, but you knowthat they will only have a good time if each of them knows at least k others at the party. (Assume that if A knows B, then B automatically knows A.) Solve your problem by designing an algorithm for finding the largest possible subset of your friends where everyone knows at least k of the others, if such a subset exists. To help you get started I’ve made a graph of “my friends”: G={'Rachel':['Ross','Monica'], 'Ross':['Rachel','Monica'], 'Monica':['Rachel','Ross'], 'Jon Snow':['Daenerys','Sansa','Arya'], 'Daenerys':['Jon Snow','Sansa','Arya','Khal Drogo'], 'Sansa':['Jon Snow','Daenerys','Arya'], 'Arya':['Jon Snow','Daenerys','Sansa'], 'Khal Drogo':['Daenerys'], 'Cersei':['Jaime'], 'Jaime':['Cersei'], 'Bart':['Milhouse'], 'Milhouse':['Bart','Lisa'],…

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 allmagic numbers in the given range that doesn’t contain digit 'm'. The number is magic if its every digit islarger than the sum of digits which are on the right side of that digit. For example, 94210 is magicnumber 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 magicnumbers excluding a given digit ‘m’ that also entered by user ?

The countSubstring function will take two strings as parameters and will return an integer that is the count of how many times the substring (the second parameter) appears in the first string without overlapping with itself. This method will be case insensitive. For example: countSubstring(“catwoman loves cats”, “cat”) would return 2 countSubstring(“aaa nice”, “aa”) would return 1 because “aa” only appears once without overlapping itself. public static int countSubstring(String s, String x) { if (s.length() == 0 || x.length() == 0) return 1; if (s.length() == 1 || x.length() == 1){ if (s.substring(0,1).equals(x.substring(0,1))){ s.replaceFirst((x), " "); return 1 + countSubstring(s.substring(1), x); } else { return 0 + countSubstring(s.substring(1), x); } } return countSubstring(s.substring(0,1), x) + countSubstring(s.substring(1), x); } public class Main { public static void main(String[] args) { System.out.println(Recursion.countSubstring("catwoman loves cats","cat"));…

Max Jones belongs to a CD (compact disc) club that allows him to buy CDs at a much lower price than his local music store charges. He wants to know how much he saves by buying all of his CDs through the club rather than through the music store. The output is the savings. The input is the number of CDs purchased, the club CD price, and thestore CD price. The algorithm should use two processing items: one for the cost of buying the CDs through the club, and the other for the cost of buying the CDs through the store. Write the algorithm using pseudocode.
