Solution: First Missing Positive
Explore how to identify the smallest missing positive integer from an unsorted array by applying the cyclic sort pattern. Understand how this approach optimizes time complexity to O(n) and space usage to a constant amount, enabling you to solve the problem efficiently without extra space. This lesson guides you through the algorithm's logic, implementation, and its advantage over naive methods.
Statement
Given an unsorted integer array, nums, return the smallest missing positive integer.
Create an algorithm that runs with an time complexity and utilizes a constant amount of space.
Note: The smallest missing positive isn’t the first positive number that’s missing in the range of elements in the input, but the first positive number that’s missing if we start from .
Constraints:
-
nums.length...
