Scylla or Charybdis? def scylla_or_charybdis(moves, n): This problem was inspired by the article "A Magical Answer to the 80-Year-Old Puzzle" in Quanta Magazine. Thanks to your recent cunning stunts, your nemesis in life is trapped inside a devious game where, for a refreshing change from the usual way of things, you get to be the Final Boss. (Everyone is the hero in their own story until they become a villain in somebody else's, after all.) This final level is a one-dimensional video game platform that reaches n-1 steps from its center to both directions. At each end of this platform exactly n steps away from the center, your two lethal friends Scylla and Charybdis are licking their lips in anticipation of a tasty morsel. Your nemesis starts at the center of this platform. To start this deadly combat of wits, she must immediately commit to her entire sequence of future moves, given to this function as a string of characters '+' (“� just a step to the ri-i-i-i-ight � ”) and '-' (move…

6.46 LAB: Subtracting list elements from max - methods (JAVA) When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. For this java program, adjust the values by subtracting each value from the maximum. The input begins with an integer indicating the number of integers that follow. Assume that the list will always contain between 1 and 20 integers. Ex: If the input is: 5 30 50 10 70 65 the output is: 40 20 60 0 5 For coding simplicity, follow every output value by a space, even the last one. Your program must define and call a method:public static int getMaxInt(int[] listInts, int listSize) Code starts here: import java.util.Scanner; public class LabProgram { /* Define your method here */ public static void main(String[] args) { /* Type your code here. */ }}

Celebrity problem A celebrity among a group of n people is a person who knows nobody but is known by everybody else. The task is to identify a celebrity by only asking questions to people of the form: ”Do you know him/her?” Solution Select two people from the group given, say, A and B, and ask A whether A knows B. If A knows B, remove A from the remaining people who can be a celebrity; if A doesn’t know B, remove B from this group. Solve the problem recursively for the remaining group of people who can be a celebrity Which design strategy does the following solution use? A-)Decrease-by-a-constant factor algorithm B-)Variable-size-decrease algorithm C-)Decrease-by-a-constant algorithm D-)Divide-and-Conquer
scheme: Q7: No Repeats Implement no-repeats, which takes a list of numbers s as input and returns a list that has all of the unique elements of s in the order that they first appear, but no repeats. For example, (no-repeats (list 5 4 5 4 2 2)) evaluates to (5 4 2). Hints: To test if two numbers are equal, use the = procedure. To test if two numbers are not equal, use the not procedure in combination with =. You may find it helpful to use the filter procedure. (define (no-repeats s) 'YOUR-CODE-HERE ) ;;; Tests (no-repeats (list 5 4 5 4 2 2)) ; expect (5 4 2)
