find nth largest number in array

When you visit other people's blogs, you can see this algorithm by accident, by the way, with C + + implementation.The simplest solution is to sort the array first and return the nth number.The following code is a quick selection algorithm (I don't

Http://www.cnblogs.com/zhjp11/archive/2010/02/26/1674227.html Today, when we look at algorithm analysis, we can see a problem where we can find the largest K value in a pile of data. The name is: design a group of N numbers, and determine the

It seems that some big companies have had a question: Find out the number of the nth in the array, of course a little change, but the essential part is this.Requirements are not sortable, time complexity cannot exceed O (n^2)A lot of ideas, I will

First, title:N Returns the and of the largest subarray in an integer array.Second, requirements:(1) n Enter an array of shapes with positive and negative numbers in the array. (2) a contiguous integer or integers in an n array make up a sub-array,

Project members: Kangzhong, Wang Zhaobo.1. Design ideas:(1) The outer while loop control end (i=n) stops.(2) Inner calculation: According to the method of non-circular array, whenever the outer layer I is incremented by 1, the array is updated, the
