Fortinet Coding Assessment Practice Set 1

90 min2 questions
Q1.
Construct String With Repeat Limit
Hash TableStringGreedyHeap (Priority Queue)
Medium50 marks

Problem Statement

In Fortinet's technical coding assessment, candidates are evaluated on clean algorithmic problem-solving for "Construct String With Repeat Limit".

Given standard input parameters adhering to Hash Table 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 Hash Table approach yields the expected solution 3.

Candidate Instructions

  • Identify the core invariant related to Hash Table.
  • Verify edge cases including empty inputs and extreme bounds.
  • Optimize time complexity before submitting.
Time:O(N log N)
Space:O(N)
Approach:Leverage Hash Table combined with String, Greedy, Heap (Priority Queue), Counting to process the input in optimal O(N log N) time complexity.

Database
Easy50 marks

Problem Statement

In Fortinet's technical coding assessment, candidates are evaluated on clean algorithmic problem-solving for "Percentage of Users Attended a Contest".

Given standard input parameters adhering to Database 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 = [2, 7, 11, 15], target = 9

Output

[0, 1]

Explanation

Applying the optimal Database approach yields the expected solution [0, 1].

Candidate Instructions

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