Question
What is the array after the first pass of the Bubble Sort algorithm?
Solution
To determine the array after the first pass of the Bubble Sort algorithm, we need to understand how the algorithm works.
- Start by considering the first two elements of the array.
- Compare these two elements and swap them if they are in the wrong order.
- Move to the next pair of elements and repeat the comparison and swapping process.
- Continue this process until the end of the array is reached.
- After the first pass, the largest element will be at the end of the array.
To illustrate this, let's consider an example array: [5, 3, 8, 2, 1]
During the first pass, the algorithm will compare and swap adjacent elements as necessary. The comparisons and swaps are shown below:
Pass 1:
- Compare 5 and 3: Swap [3, 5, 8, 2, 1]
- Compare 5 and 8: No swap [3, 5, 8, 2, 1]
- Compare 8 and 2: Swap [3, 5, 2, 8, 1]
- Compare 8 and 1: Swap [3, 5, 2, 1, 8]
After the first pass, the array will be [3, 5, 2, 1, 8]. The largest element, 8, has moved to the end of the array.
