peak6 Coding Assessment Practice Set 1

90 min2 questions
Q1.
Maximum Profit of Operating a Centennial Wheel
ArraySimulation
Medium50 marks

Problem Statement

In peak6's technical coding assessment, candidates are evaluated on clean algorithmic problem-solving for "Maximum Profit of Operating a Centennial Wheel".

Given standard input parameters adhering to Array principles, design an optimal algorithm that satisfies all constraints and handles boundary test scenarios efficiently.

Ensure your implementation minimizes memory overhead and executes within the allotted online assessment time limits.

Input Format

  • The first line specifies the dimensions or count of test elements N.
  • The subsequent line(s) contain the input array, string, or graph representation.

Output Format

  • Print the computed result adhering to the required return format.

Constraints

  • 1 <= N <= 10^5
  • -10^9 <= element[i] <= 10^9
  • Time Limit: 2.0 seconds
  • Memory Limit: 256 MB

Edge Cases

  • Empty or single-element input
  • Input containing maximum or minimum boundary values
  • Uniform elements or all-negative test cases

Sample Test Cases

Example 1

Input

nums = [1, 2, 3, 4, 5], k = 3

Output

3

Explanation

Applying the optimal Array approach yields the expected solution 3.

Candidate Instructions

  • Identify the core invariant related to Array.
  • Verify edge cases including empty inputs and extreme bounds.
  • Optimize time complexity before submitting.
Time:O(N)
Space:O(1)
Approach:Leverage Array combined with Simulation to process the input in optimal O(N) time complexity.
