Given three int variables that have been given values, areaCode, exchange, and lastFour, write a string expression whose value is the string equivalent of each these variables joined by a single hyphen (-) So if areaCode, exchange, and lastFour, had the values 800, 555, and 1212, the expression's value would be "800-555-1212". Alternatively, if areaCode, exchange, and lastFour, had the values 212, 867 and 5309 the expression's value would be "212-867-5309".

The internet enables people to network, join a cause, take a poll, etc. Your program will prompt the user for a description of a poll to be taken and then prompt 5 users for a response of 1-10 (1 being a 'poor' response; 10 being the 'best' response).Your program does not have to validate that the user entered 1-10. We'll do that type of checking later.Your program must use a string data type to store the poll description and a Python list data type to save the integer responses of the 5 user responses.Your output should list all the responses stored in the list, the highest given response, the lowest given response and the average of the 5 responses. See sample input and utput below.Review powerpoint 3, slide 21 for an example if you need one.

You are given a string ternary_expr which represents a random nested ternary expression, you need to evaluate this expression, and report the result. Assumption can be as follows: ● ternary_expr only contains digits, ‘?’, ‘:’, ’T’, ‘F’ where ’T’ is true and ‘F’ is false. ● ternary_expr contains only one-digit numbers (i.e. in the range [0, 9]) The ternary expressions group right-to-left, and the result of the expression will always evaluate to either a digit, 'T' or 'F'. Requirements 1. Way of modeling the problem with the cost implications without using Stacks.

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"));…
