nth_element是stl中的一个库函数,它会使迭代器nth所指的元素与整个[first,last)完整排序后.同一个位置的元素同值.即找到完整排序时第n位的正确值. 但这个函数与完整排序的区别在于: 1.它只关注第n个,只保证小于该值的元素在其左边,大于等于的在其右边,但并不保证其完全有序. 2.它的时间复杂度在O(N),而许多排序所用的复杂度为O(NlogN).对于特定的找到第k大数的问题,所花时间是好于排序的. 它的原理思想如图 这个算法的思路很像快排中partation函数.首先有一…

Given a list of non negative integers, arrange them such that they form the largest number. For example, given [3, 30, 34, 5, 9], the largest formed number is 9534330. Note: The result may be very large, so you need to return a string instead of an i…

Given an array which consists of non-negative integers and an integer m, you can split the array into m non-empty continuous subarrays. Write an algorithm to minimize the largest sum among these m subarrays. Note:Given m satisfies the following const…
