Contains Duplicate Leetcode 217 Interview Handbook Can you solve this real interview question? contains duplicate given an integer array nums, return true if any value appears at least twice in the array, and return false if every element is distinct. If duplicates exist, the set will contain fewer elements. the logic is identical to the earlier approach — this version is just a shorter and more concise implementation of it.

In this guide, we solve leetcode #217 in python and focus on the core idea that makes the solution efficient. you will see the intuition, the step by step method, and a clean python implementation you can use in interviews. Leetcode 217: contains duplicate given an integer array nums, return true if any value appears at least twice in the array, and return false if every element is distinct. Below is my solution and some test cases. this solution has a linear time complexity o (n) and a linear space complexity o (n), where n is the length of the input list nums. First, we sort the array nums. then, we traverse the array. if there are two adjacent elements that are the same, it means that there are duplicate elements in the array, and we directly return true. otherwise, when the traversal ends, we return false. the time complexity is \ (o (n \times \log n)\), where \ (n\) is the length of the array nums.
