Kth largest quickselect

CodingAlgorithms & data structuresMid–Senior~20 min

Given an integer array nums and an integer k, return the k-th largest element in the array. Duplicates count by position, so the k-th largest is the element at index k-1 if the array were sorted descending. 1 <= k <= len(nums) <= 1e5.

Implement
find_kth_largest(nums: list[int], k: int) → int
Examples
in[[3,2,1,5,6,4],2]out5
What a strong answer looks like

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
