Example: Largest Element in an array #include <stdio.h> int main() { int n; double arr[100]; printf("Enter the number of elements (1 to 100): "); scanf("%d", &n); for (int i = 0; i < n; ++i) { printf("Enter number%d: ", i + 1); scanf("%lf", &arr[i]); }...
Here, we are going to implement a C Program to Find Largest Element in an Array using Recursion.
题目地址:https://leetcode.com/problems/kth-largest-element-in-an-array/description/题目描述Find the kth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element.
Find the kth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element. For example, Given[3,2,1,5,6,4]and k = 2, return 5. Note: You may assume k is always valid, 1 ≤ k ≤ array's length. 链接:http:...
public int findKthLargest(int[] nums, int k) { Arrays.sort(nums); return nums[nums.length - k]; } 解法二 我们没必要把所有数字正确排序,我们可以借鉴快排中分区的思想,这里不细讲了,大家可以去回顾一下快排。 随机选择一个分区点,左边都是大于分区点的数,右边都是小于分区点的数。左部分的个数记...
215. Kth Largest Element in an Array 题目大意:给定无序数组求第k大,经典面试题 题目思路:利用快速排序,每次定一个轴,比轴大的放左边,小的放右边,如果左边的数量小于k,则第k大在右边,反之在左边,每次去找就好了 时间复杂度&&空间复杂度:O(n)(需要找的总共次数为n/2+n/4+…+1 = 2n-1...
