Solution: First Missing Positive
Explore how to solve the first missing positive integer problem efficiently by implementing a cyclic sort algorithm. This lesson helps you understand placing elements in their correct positions in O(n) time and constant space, enabling you to find the smallest missing positive integer without extra storage or slow sorting.
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...
