Problem: First Missing Positive
Explore how to identify the smallest missing positive integer in an unsorted integer array efficiently. Learn to implement a cyclic sort technique that rearranges elements in-place, achieving linear time and constant space complexity. Understand step-by-step how this method leverages the array as its own hash map to solve the problem.
