Kth largest element in array

Home | Coding Interviews | Searching and Sorting | Kth largest element in array

Given an integer array nums and an integer k, return the kth largest element in the array.

Note that it is the kth largest element in the sorted order, not the kth distinct element.

class Solution:
    def findKthLargest(self, nums, k):
        if not nums: return
        pivot = random.choice(nums)
        left =  [x for x in nums if x > pivot]
        mid  =  [x for x in nums if x == pivot]
        right = [x for x in nums if x < pivot]
        
        L, M = len(left), len(mid)
        
        if k <= L:
            return self.findKthLargest(left, k)
        elif k > L + M:
            return self.findKthLargest(right, k - L - M)
        else:
            return mid[0]

A transformation sequence from word beginWord to word endWord using a dictionary wordList is a sequence of words beginWord -> s1 -> s2 -> ... -> sk such that:

Every adjacent pair of words differs by a single letter.

Every si for 1 <= i <= k is in wordList. Note that beginWord does not need to be in wordList.

sk == endWord

Given two words, beginWord and endWord, and a dictionary wordList, return all the shortest transformation sequences from beginWord to endWord, or an empty list if no such sequence exists. Each sequence should be returned as a list of the words [beginWord, s1, s2, ..., sk].

Given an array of distinct integers candidates and a target integer target, return a list of all unique combinations of candidates where the chosen numbers sum to target. You may return the combinations in any order.

The same number may be chosen from candidates an unlimited number of times. Two combinations are unique if the frequency of at least one of the chosen numbers is different.

There are a total of numCourses courses you have to take, labeled from 0 to numCourses - 1. You are given an array prerequisites where prerequisites[i] = [ai, bi] indicates that you must take course bi first if you want to take course ai.

For example, the pair [0, 1], indicates that to take course 0 you have to first take course 1.

Return true if you can finish all courses. Otherwise, return false.
