Solution: First Missing Positive
Discover how to solve the problem of finding the first missing positive integer in an unsorted array by applying cyclic sort. This lesson helps you implement an O(n) time and constant space algorithm that places numbers in their correct positions and identifies the smallest missing positive efficiently.
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...
