Memory-Optimized Algorithmic Solution | Dataford Interview Questions

Can you implement a solution to a specific algorithmic problem while optimizing for memory constraints?

Implement find_duplicate(nums). The input contains n + 1 integers, each in the range 1 through n, with exactly one value duplicated. Return the duplicated value without modifying nums and using O(1) extra space.

Input: a list of integers. Output: the duplicated integer.

Constraints

2 <= nums.length <= 100001
nums.length - 1 = n
1 <= nums[i] <= n
Exactly one value is duplicated
The input list must not be modified
Use O(1) auxiliary space

Function Signature

def find_duplicate(nums):
