Every question in the paper gets a full exam-length answer in the app — organised by marks, the way a topper writes it.
Explain Bubble Sort with an example and analyze its best-case and worst-case time complexity.
Bubble Sort repeatedly swaps adjacent elements; best-case O(n), worst-case O(n^2).

Explain Merge Sort using Divide and Conquer and derive its time complexity.
Merge Sort divides the array, sorts subarrays, and merges; time complexity is O(n log n).

Explain Selection Sort with a suitable example and analyze its time complexity.
Selection Sort selects the minimum element; time complexity is O(n^2).

Solve the recurrence relation of Merge Sort using the recursion tree method.
The recurrence relation T(n) = 2T(n/2) + O(n) solves to T(n) = O(n log n).

Analyze the time complexity of the following nested loop: for i = 1 to n for j = 1 to n print(i, j)
The time complexity is O(n^2) due to the nested loops.
