A colleague you work with is tired of people calling binary search on unsorted arrays (they keep reporting getting back incorrect answers). They propose the following defensive variant: public int defensiveBinarySearch(int[] array , int key) {      Collections.sort(array); // ensure the input list is sorted       return binarySearch(array, key); // run normal binary search } What is the Big O runtime of your colleague’s defensive version?

Among the various sorting algorithms listed below that were discussed in the chapter and in the lectures, which of the following sorting algorithms guarantees the best (fastest) Big O in terms best, average and worst case?

What does this modified linear search algorithm do? public static boolean mysteryLinearSearch(int[] a) {    for (int value : a) {        if (value % 2 == 0) {            return true;        }    }    return false;}

This code tries to find a number. What’s the issue? public static int badSearch(int[] data, int value) {      for (int v : data) {           if (v == value) return v;      }      return -1; // not found 🙁 }

What is the AVERAGE case time complexity of linear search? 

3. g) It would be easier to filter out the image frequency if the LO frequency was changed to 2500 MHz.

I understand and agree that the following are not allowed during this proctored test. No use of paper or electronic notes No books No electronic devices (e.g., second monitors, phones, ipads, or other devices that have access to the internet) No electronic searches No AI tools (e.g., ChatGPT, etc.) No external help No other browsers or browser tabs open except for the tab used for completing the test. No other apps running that share my screen with others (except for shared screen with the proctor) No attempt to take screen shots of the questions I also understand that while taking this exam, I must Remain visible and within the camera frame. Maintain my eyes on the monitor which is used to take the exam. Make sure the room that I am in is free of background noise or other interruptions.  

Explain the General Adaptation Syndrome in 3-5 sentences.

What is printed after this code runs? int a = {4, 2, 7, 1,…”…

Which of the following is true about QuickSort?
