Previous HackWithInfy Questions

The Questions from previous HackWithInfys play a crucial role in preparation for the examination. These questions provide insight into the type and difficulty level of questions that can be expected in the actual program.

Question 1

As the manager of the hotel, you have N guests to attend to, and each guest has a happiness value (Ci) that depends on when they are served. The unhappiness of a guest is determined by the difference between their happiness value (Ci) and the time (x) they are served, which is calculated as |Ci – x|. Your goal is to find the minimum total unhappiness by serving all guests in any order you choose.

Please note that at a given time, only one guest can be served, and each guest takes exactly one unit of time to be served.

Here are the constraints:

  • 1 <= N <= 10^3
  • 1 <= Ci <= N

For example:

Input: 4 2 2 3 3

Output: 2

Input: 4 1 1 1 1

Output: 6

Question 2

You’re tasked with finding the total number of positive integer pairs (A, B) where A, B <= N, A^B <= X and A+B is divisible by D. Given the inputs N, X and D, return the result modulo 10^9+7 as the total number of pairs can be large.

Here’s an example: for the inputs 4, 3, 2, there are 6 pairs that meet the conditions: (1,1), (1,3), (2,2), (3,1), (3,3), (4,4).

And for debugging purposes, a sample test case of 100, 121, 2 should return 4778.

Question 3

Given an array of size N and the limit M, find the maximum number of triplets that can be formed such that each element of the array is <= M. A triplet is considered valid if it meets either of the following criteria:

All numbers in the triplet are the same.

The numbers are consecutive.

Each element in the array can only belong to one triplet.

Constraints:

  • 1 <= N <= 10^5
  • 1 <= M <= 10^4
  • 1 <= arr[i] <= M

Example:

Input:

4 2

1 2 2 2

Output:

1

Explanation: Only one triplet can be formed {2,2,2}

Question 4

Find the minimum possible absolute difference between the maximum and minimum sum of elements in 4 non-empty contiguous subsequences of an array A of N elements by making 3 cuts.

Constraints:

  • 4 <= N <= 10^5
  • 1 <= A[i] <= 10^4

Input:

10

10 71 84 33 6 47 23 25 52 64

Output:

36

Question 5

You are given N people and K days, each day represented by an array of N numbers, indicating the order in the people who arrived at the theatre. Your task is to find the largest group of people who arrive in the same order for all K days.

Constraints:

  • 1 <= N <= 1000
  • 1 <= K <= 10
  • 1 <= a[i][j] <= N

Sample Input:

N=4, K=3

Day 1: [1, 3, 2, 4]

Day 2: [1, 3, 2, 4]

Day 3: [1, 4, 3, 2]

Sample Output:

3 (people 1, 3, 2 arrive in the same order for all K days)

Question 6

You are given a string of length n consisting of numbers and question marks (# represents a mine and the number represents the sum of the number of mines in the adjacent cells). Your task is to fill the question marks with either 0 or 1 in such a way that the string represents the correct sum of mines in the adjacent cells. Return the number of ways to fill the question marks.

Constraints:

  • 1 <= n <= 10^5

Example Input:

??0?1?

Example Output:

2

Example explanation: Two possible ways to fill the question marks are #1001# and 00001#.

Question 7

Akshat has N squares, each with a side length of S[i]. Your task is to help him create K pyramids using all N squares. The i-th pyramid has C[i] squares. The beauty of a structure is defined as the sum of the side length of the top and bottom squares of all K pyramids. Find the maximum beauty of a structure that can be created.

Input:

  • First line: an integer N representing the number of squares.
  • Second line: an integer K representing the number of pyramids to be created.
  • Next N lines: an integer S[i] representing the side length of each square.
  • Next K lines: an integer C[i] representing the number of squares in the i-th pyramid.

Constraints:

  • 1 <= N <= 10^5
  • 1 <= K <= 10^5
  • 1 <= S[i] <= 10^5
  • 1 <= C[i] <= 10^5
