Write a function called doubleMeanings that takes a reference to an unordered_map of multi-word strings to their acronyms. Return a pointer to an unordered_set of all acronyms that represent more than one string (appear in the map more than once). For example, if a map stored the following data: {“Wisconsin Tourism Federation”=”wtf”, “intellectual property”=”ip”, “internet protocol”=”ip”, “department of aging”=”doa”, “in particular”=”ip”, “dead or alive”=”doa”, “laughing out loud”=”lol”, “what the font”=”wtf”} your function should return a pointer to an unordered_set containing: {“wtf”, “ip”, “doa”} If the map is empty or does not contain any acronyms more than once a pointer to an empty set should be returned. Do not make any assumptions about the key values in the passed in map. They could be in any order, start with any letter (not necessarily the same as their value’s first letter) and be in any casing. Do not alter the contents of the map. You may create the unordered_set your function should return a pointer to and only one other data structure to help you solve this problem. To receive full credit your solution must run in O(n) time where n is the size of the passed in map.

Write a function evenSum that could be added to the LinkedList class from lecture that returns the sum of the values in even indexes in the list of integers. Assume we are using 0-based indexing where the first value in the list has index 0, the second value has index 1 and so on. The values we are interested in are the ones with even indexes (the value at index 0, the value at index 2, the value at index 4, and so on). For example, suppose that a variable named list stores this sequence of values: {1, 7, 2, 2, 39, 45, 40, 5} then the call: list.evenSum() should return the value 82 (1 + 2 + 39 + 40). Notice that what is important is the position of the numbers (index 0, index 2, index 4, etc), not whether the numbers themselves are even. If the list is empty, your function should return a sum of 0. Assume that we are adding this function to the LinkedList class as seen in lecture and as shown below. You may not call any other functions of the class to solve this problem. class LinkedList { private: ListNode* front; }

Write the output produced by the following function when passed each of the following queues: Assume that a stack prints in {bottom, …, top} order, a queue displays in {front, …, back} order and maps print as {key1=value1, … keyN=valueN}. void mystery(queue& q) { stack s; map m; int oldSize = q.size(); for (int i = 0; i < oldSize; i++) { if (i % 2 == 0) { q.push(q.front()); q.pop(); } else { s.push(q.front()); q.pop(); } m = i; } for (int i = 0; i < oldSize; i++) { if (i % 2 == 0) { q.push(q.front()); q.push(m); q.pop(); } else { q.push(s.top()); s.pop(); } } cout
