Error: do not familiar the pattern of quick sort, cannot write the code. Use the idea of quick, pivot. Which the position of pivot tell us how many number smaller than pivot, and it can inference that the num[pivot] is the kth largest number: if(k == kth largest of pivot) return ...
【leetcode】Kth Largest Element in an Array (middle)☆ 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....
Largest Number 给定一组数,返回把这组数连接起来之后能组成的最大的数。由于最后的结果可能非常大,所以返回string 这道题的tag是排序 根据int数组构造一个string数组,对这个string数据进行排序,排序的规则是s1 + s2 > s2 + s1(比较两个strings比较的是从头到尾各个字符的Ascii值)。所以这个排序之后的结果就是我...
Explanation: 6 is the largest integer, and for every other number in the array x, 6 is more than twice as big as x. The index of value 6 is 1, so we return 1. Example 2: Input: nums = [1, 2, 3, 4] Output: -1 Explanation: 4 isn't at least as big as twice the value...
