Apply Quick sort on a given sequence 7 11 14 6 9 4 3 12. What is the sequence after first phase, pivot is first element? a. 7 6 14 11 9 4 3 12 b. 7 6 4 3 9 14 11 12 c. 6 3 4 7 9 14 11 12 d. 6 4 3 7 11 9 14 12

The correct answer is c. 6 3 4 7 9 14 11 12

Here's the step-by-step process:

1. Choose the first element in the list as the pivot, which is 7.

2. Partition the list into two sub-lists - elements less than the pivot and elements greater than the pivot.

3. The elements less than the pivot are 6, 4, and 3. The elements greater than the pivot are 11, 14, 9, and 12.

4. Combine the elements less than the pivot, the pivot, and the elements greater than the pivot. This gives us the sequence after the first phase: 6 3 4 7 9 14 11 12.

The correct answer is c. 6 3 4 7 9 14 11 12.

Here's the step-by-step process:

1. We choose the first element as the pivot, which is 7.

2. We then rearrange the sequence in such a way that all elements less than the pivot are to its left, and all elements greater than the pivot are to its right.

3. The sequence becomes: 6 3 4 7 9 14 11 12.

So, after the first phase of Quick sort, the sequence is 6 3 4 7 9 14 11 12.

The answer is c. 6 3 4 7 9 14 11 12.

Here's the step-by-step process:

1. Choose the first element in the list as the pivot, which is 7.

2. Partition the list into two sub-lists - elements less than the pivot and elements greater than the pivot.

3. The elements less than the pivot are 6, 4, 3. The elements greater than the pivot are 11, 14, 9, 12.

4. Combine the elements less than the pivot, the pivot, and the elements greater than the pivot. This gives us the sequence after the first phase: 6 3 4 7 9 14 11 12.
