One day Vasya showed Petya an array consisting of n integers and suggested finding the array's median. Petya didn't even look at the array and said that it equals x. Petya is a very honest boy, so he decided to add several numbers to the given array so that the median of the result...
1 ≤ x ≤ 105) — the initial array's length and the required median's value. The second line containsnspace-separated numbers — the initial array. The elements of the array are integers from1to105. The array elements are not necessarily different....
You want to make the median of the array the largest possible using at most kk operations. The median of the odd-sized array is the middle element after the array is sorted in non-decreasing order. For example, the median of the array [1,5,2,3,5][1,5,2,3,5] is 33. The first...
Codeforces Round #550 (Div. 3) E 【数学】 题目链接:http://codeforces.com/contest/1144 把字符串当作26进制数,通过 (L+R)/2 ,取中间值再转成字符串就是答案。 因为字符串的长度很大,算出来的数会溢出,所以需要一些技巧。 假设有两个字符串 abc, efg 那么就有 通过不断的 % 26 得到每个位的数字...
You are given an array aa of nn integers, where nn is odd. You can make the following operation with it: Choose one of the elements of the array (for example aiai) and increase it by 11(that is, replace it with ai+1ai+1). ...
In one well-known algorithm of finding thek-th order statistics we should divide all elements into groups of five consecutive elements and find the median of each five. A median is called the middle element of a sorted array (it's the third largest element for a group of five). To incre...
Can someone share their thoughts on the following question : Given a array of n elements. You have to find the median of difference of pairs. For Example: Lets say the elements are {1,2,4,5}. So the pairs will be {(1,2),(1,4),(1,5),(2,4),(2,5),(4,5)}. The array ...

Leetcode Median of Two Sorted Arrays There are two sorted arrays A and B of size m and n respectively. Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)). 将两个有序数组合并,注意题目求得是the median of the two sorted array, 当m+n是...
