Set 1 • 90 min
Problem Statement

In LiveRamp's technical coding assessment, candidates are evaluated on clean algorithmic problem-solving for "Largest Time for Given Digits".

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.

Candidate Instructions
  • ▸Identify the core invariant related to Array.
  • ▸Verify edge cases including empty inputs and extreme bounds.
  • ▸Optimize time complexity before submitting.
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
