Detect Duplicates in Array

Problem

Given an array of integers nums, write a function that returns true if any value appears more than once and false if all values are distinct. The input is a list of integers, and the output is a boolean.

Constraints

• 1 <= len(nums) <= 10^5
• -10^9 <= nums[i] <= 10^9
• The function should handle negative numbers and repeated values
