Which sorting algorithm is known for its divide-and-conquer approach, where it repeatedly divides the input array into smaller subarrays until they are sorted and then merges them back together?

  1. Bubble Sort

  2. Selection Sort

  3. Merge Sort

  4. Quick Sort


Correct Option: C
Explanation:

Merge Sort follows a divide-and-conquer strategy, dividing the input array into smaller subarrays, sorting them recursively, and then merging them back together to obtain the sorted array.

Which sorting algorithm repeatedly compares adjacent elements and swaps them if they are in the wrong order, continuing until no more swaps are needed?

  1. Bubble Sort

  2. Selection Sort

  3. Merge Sort

  4. Quick Sort


Correct Option: A
Explanation:

Bubble Sort repeatedly compares adjacent elements and swaps them if they are in the wrong order, moving the larger elements to the end of the array with each pass.

Which sorting algorithm finds the minimum element from the unsorted portion of the array and places it at the beginning, then repeats this process until the entire array is sorted?

  1. Bubble Sort

  2. Selection Sort

  3. Merge Sort

  4. Quick Sort


Correct Option: B
Explanation:

Selection Sort repeatedly finds the minimum element from the unsorted portion of the array and places it at the beginning, reducing the unsorted portion with each iteration.

Which sorting algorithm selects a pivot element, partitions the array into two subarrays based on the pivot, and recursively applies the same process to the subarrays until the entire array is sorted?

  1. Bubble Sort

  2. Selection Sort

  3. Merge Sort

  4. Quick Sort


Correct Option: D
Explanation:

Quick Sort selects a pivot element, partitions the array into two subarrays based on the pivot, and recursively applies the same process to the subarrays, achieving efficient sorting.

Which sorting algorithm builds a sorted array one element at a time by inserting each unsorted element into its correct position in the sorted portion of the array?

  1. Bubble Sort

  2. Selection Sort

  3. Merge Sort

  4. Insertion Sort


Correct Option: D
Explanation:

Insertion Sort builds a sorted array one element at a time by inserting each unsorted element into its correct position in the sorted portion of the array.

Which sorting algorithm is known for its ability to sort large arrays efficiently by dividing the array into smaller subarrays, sorting them recursively, and then combining them back together?

  1. Bubble Sort

  2. Selection Sort

  3. Merge Sort

  4. Quick Sort


Correct Option: C
Explanation:

Merge Sort is known for its efficient sorting of large arrays by dividing them into smaller subarrays, sorting them recursively, and then combining them back together.

Which sorting algorithm is often used for sorting linked lists, where it repeatedly finds the minimum element from the unsorted portion of the list and moves it to the front?

  1. Bubble Sort

  2. Selection Sort

  3. Merge Sort

  4. Quick Sort


Correct Option: B
Explanation:

Selection Sort is often used for sorting linked lists, where it repeatedly finds the minimum element from the unsorted portion of the list and moves it to the front.

Which sorting algorithm is based on the idea of repeatedly swapping adjacent elements if they are in the wrong order, moving the larger elements to the end of the array?

  1. Bubble Sort

  2. Selection Sort

  3. Merge Sort

  4. Quick Sort


Correct Option: A
Explanation:

Bubble Sort is based on the idea of repeatedly swapping adjacent elements if they are in the wrong order, moving the larger elements to the end of the array.

Which sorting algorithm is known for its ability to sort arrays in place, meaning it modifies the original array without creating a new one?

  1. Bubble Sort

  2. Selection Sort

  3. Merge Sort

  4. Quick Sort


Correct Option: D
Explanation:

Quick Sort is known for its ability to sort arrays in place, meaning it modifies the original array without creating a new one.
