how to find average of 2 numbers

Question: Find the M-largest number in a group of unordered numbers. For example, in a group of unordered numbers: 3, 2, and 321, find the 2nd-largest number. Obviously, here we can see that it is number 3. Resolution: There are many solutions to this type of question. The s

Preface I had a weekend with a couple of university friends. I was very happy that everyone was very sensible and working hard. I have graduated from Yahoo for two years, but I have no question about salary, haha, I had a good chat, but I didn't write much code over the weekend. Here I have a few questions on the 9du OJ, Which I recorded by the way (PS: it seems I have recorded this question before, no matter what) question Description: In an integer array, all the

Topic:Given an array S of n integers, is there elements a, b, c in S such That a + b + c = 0? Find all unique triplets in the array which gives the sum of zero.Note:the solution set must not contain duplicate triplets.For example, given array S = [-1, 0, 1, 2,-1, -4],a solution Set is:[[-1, 0, 1], [-1,-1, 2]]Code:The title is simple: Pick three

Given an array of s, try to find 3 numbers A, B, C, making a+b+c=0. That is to find out all the 0 and 3 numbers from the collection. For example: Set s={-1,0, 1, 2,-1, 4}, the 3-digit number that satisfies the condition has 2 pair

numbers in a given array, this is slightly more complex than the two. Step analysis, set these three numbers to A,b,c: (1) The number in the array is all different or the result x=a^b^c, but X is not one of a,b,c, assuming x=a, then b^c=0 description b=c, with the topic given the conditions of contradiction. (2) Set F (n) can be as in

Title Description:In an array of integers, except for two digits, the other numbers appear two times. Write a program to find the two only occurrences of the number. Requires time complexity O (n), Spatial complexity O (1).For example {2,4,3,6,3,2,5,5}, Output {4,6}Analytical:The space Complexity of O (1) Severed the idea of using hash-table, Time complexity O (n) cut off the sort of thinking.How do you tel

First, title:If there is a number in the array that appears more than half the length of the array, find this number. For example, enter an array of length 9 {1,2,3,2,2,2,5,4,2}. Since the number 2 appears in the array 5 times, which exceeds half the length of the array, the output is 2. Output 0 If it does not exist.Second, analysis:1). Violence statistics (ergo

First, make it clear that this aspect of the problem is designed to be an array of knowledge points for finding problems. The specific approach to such a lookup operation is three workarounds:1. Brute force algorithm, multiple for loop, very high time complexity 2. First sort, then left and right, but this will destroy the original array of the following table 3. Using the hash table, directly positioning elements, very little time complexity　　Twosums

beginning of each loop, where I define INT_MAX, so all the rows need to be traversed one by one times.2. In each row wheel cycle, do not forget to determine whether the corresponding value of the number of columns of the index has reached the maximum value.3. Note that the Minrows array is updated only after the end of the row round cycle.============================================================================================================In ad

, update: bestlength = length.Set start and end to the number found just now, length = 1, and then repeat the above operation. The final bestlength is the maximum number of consecutive natural numbers.Since hash search and other operations can be completed within the O (1) time complexity, the hash method can meet the O (n) time complexity. Method 3: bitmapUse bitmap. Method 2 is similar.The bitmap size is related to the maximum integer. Each digit in
