Grokking the Coding Interview Patterns in Python

Contains Duplicate

Explore how to identify duplicate integers in an array by applying efficient algorithms. Learn to solve this common coding interview problem using optimal time and space complexities. Practice implementing a solution that runs in linear time and uses linear space, reinforcing your problem-solving skills for technical assessments.

We'll cover the following...

Statement

For a given array of integers, nums, return TRUE if it contains duplicates. Otherwise, return FALSE.

Constraints:

  • 1≤1 \leq nums.length ≤ ...
