Solution: Find K Largest Elements in the List

Statement

Given a list of integers, nums, and a positive integer, k, find the k largest elements in the list.

Constraints:

• $1 \leq$ k $\leq$ nums.length $\leq 10^3$

• $-10^4 \leq$ nums[i] $\leq 10^4$

Solution 1: Utilizing sort

In this solution, we sort the given list of numbers in descending order, meaning the largest numbers come first. Then, we select the first k elements from the sorted list, which are the k largest elements in the original list, and return them.

Let’s look at how the implementation of the algorithm works:

• The nums undergoes sorting in descending order utilizing the sort method with the reverse=True parameter.

• Through slicing notation nums[:k], the operation retrieves the first k elements from the sorted list.

• These first k elements, now representing the largest values, are returned as the output.
