Given an array of integers, what is the logic used in the Bubble Sort algorithm to sort the elements?

• Divide the array into two halves and sort each half individually.

• Compare each pair of adjacent elements and swap them if they are in the wrong order.

• Select a pivot element and partition the array into two subarrays, then recursively sort each subarray.

• Build a binary heap and repeatedly extract the minimum element.

  
  

What is the key concept behind the Binary Search algorithm for finding an element in a sorted array?

• Comparing each element with the target element sequentially.

• Sorting the array using a pivot element.

• Dividing the array into two halves and eliminating one half based on the comparison with the target element.

• Swapping adjacent elements until the array is sorted.
