Relate to a recursive sorting algorithm called QuickSort, which is described as follows: A one-element list is already sorted; no further work is required. Otherwise, take the first element in the list, call it the pivot element, then walk through the original list to create two new sublists, $L_{1}$ and $L_{2}.$ $L_{1}$ consists of all elements that are less than the pivot element and $L_{2}$ consists of all elements that are greater than the pivot element. Put the pivot element between $L_{1}$ and $L_{2}.$ Sort each of L1 and L2 using QuickSort (this is the recursive part). Eventually all lists will consist of 1 element sublists separated by previous pivot elements, and at this point the entire original list is in sorted order. This is a little confusing, so here is an example, where pivot elements are shown in brackets: Original list: 6, 2, 1, 7, 9, 4, 8; After 1st pass: 2, 1, 4, [6], 7, 9, 8; After 2nd pass: 1, [2], 4, [6], [7], 9, 8; After 3rd pass: 1, [2], 4, [6], [7], 8, [9] Sorted. How many comparisons between list elements are required for pass 1 of QuickSort in the example list?

Which of the following code segments correctly creates a four-element array and initializes it so that each element stores its index? For example, the element stored at index 2 is 2. I int[] a={0, 1, 2, 3}; II int[] a={1, 2, 3, 4}; III int[] a=new int[4]; for (int i=0; i<4; i++) a[i]=i; a. I only, b. I and II, c. II and III, d. I and III, e. I, II, and III.

Other Quizlet setsRelated questionsFor most of our clients who present with the postural distortion pattern known as upper crossed syndrome, it is important, perhaps absolutely necessary, to include thoracic spinal joint mobilization technique into extension as part of the treatment plan to address the thoracic hyperkyphosis.
Tight hip flexor musculature causes excessive anterior tilt of the pelvis… hyperlordosis of the lumbar spine… hyperkyphosis of the thoracic spine… hypolordosis of the lower neck with hyperextension of the head at the atlanto-occipital joint… forward head carriage… tight posterior neck muscles… headache.
Slumped spinal posture is characterized by slumped postural dysfunction from the pelvis to the head. Assessment is made upon static postural examination.
The longer we allow ourselves to sit in a slumped posture, the more imbalanced is our spine and the more gravity pulls our trunk toward flexion.
Scoliosis is a lateral flexion deformity of the spine. The spine should have curves in the sagittal plane, but a frontal plane curve is a scoliosis.
Case Study: Kori is a 30-year-old store clerk. Her low back has been tight for as long as she can remember, but she never had any pain until recently.
For the client with lower crossed syndrome, it is also important to recommend moist heat followed by stretching of the low back and hip flexor musculature.
If consistent manual therapy care is given, including heat, massage, and stretching, lower crossed syndrome responds very well to treatment.
Assessment of lower crossed syndrome is made by the characteristic postural dysfunction of increased anterior pelvic tilt with hyperlordotic lumbar spine.
Vladimir Janda’s lower crossed syndrome is characterized by increased anterior tilt of the pelvis and a hyperlordotic lumbar spine.
