Which of the following algorithms finds the number of integers greater than 5 in a list of n integers a1, a2, . . . , an? Sort the list in non-decreasing order. Iterate over the list and for each integer ai, check if it is greater than 5. If it is, increment the count variable by 1. Return the count variable. Create a new list of all integers greater than 5 by iterating over the list and appending each integer greater than 5 to the new list. Return the length of the new list. Create a hash table to store the count of each integer in the list. Iterate over the hash table and for each integer i greater than 5, add the count of i to a variable. Return the variable. Initialize a count variable to 0. Iterate over the list and for each integer ai, check if it is greater than 5. If it is, increment the count variable by 1. Return the count variable.

Write a program that first reads a list of 5 integers from input. Then, read another value from the input, and output all integers less than or equal to that last value. Ex: If the input is: 50 60 140 200 75 100 the output is: 50 60 75 For coding simplicity, follow every output value by a space, including the last one. Then, output a newline. Such functionality is common on sites like Amazon, where a user can filter results.
Question 5 Assume that the following method is in a class called DLL (not same as KWLinkedList). What does this method do? public void method_LI( ) { KWLinkedList<Integer> list = new KWLinkedList<Integer>( ); list.add(2); list.add(-1); list.add(0); list.add(1); list.add(0); ListIterator<integer> iter = list.listIterator(); while(iter.hasNext()) { if (iter.next() == 0) iter.remove(); } if( iter.hasPrevious() ) System.out.println("END"); else while(iter.hasNext()) System.out.print(iter.next() + " "); } Removes the nodes having 0 as its data and prints END. Removes the nodes having 0 as its data and prints 2 -1 1 Removes the nodes having 0 as its data and prints 1 -1 2 Prints 2 -1 0 1 0 without removing anything.
Assume that the following method is within the KWLinkedList class, what does this method do? public boolean undefined(E item) { if(head == null) return false; Node<E> p = head.next; Node<E> newNode= new Node<E>(item, p); newNode.prev = head; head.next = newNode; p.prev = newNode; size++; return true; } nserts a new node with its data as item at the front of the list. Inserts a new node with its data as item after the first node of the list. Deletes the node with its data as item. Inserts a new node with its data as item, at the end of the list.
Create a single regular expression that matches a string representing a comma separated list of variable names such as: hello, get_max, sum3Additional notes: A variable name consists of letters, digits, and underscores but cannot start with a digit. There is exactly one space after every comma. No other spaces are allowed. Commas and spaces are not allowed before the first name and after the last name. An empty string is considered a match. It is not a match if the list is not properly formed or if one of the variable names is invalid.
Given list colors = [‘red’ , ‘green’ , ‘blue’] followed by the assignment colors[2]=‘yellow’ Will result in the list colors containing [‘red’ , ‘green’ , ‘yellow’] True or false?
Make a list called sandwich_orders and fill it with the names of varioussandwiches. Then make an empty list called finished_sandwiches. Loop throughthe list of sandwich orders and print a message for each order, such as I madeyour tuna sandwich. As each sandwich is made, move it to the list of finishedsandwiches. After all the sandwiches have been made, print a message listing each sandwich that was made.
Results are not the same at the end and I do not get the right result after choosing number 3.
