The K-th largest number of ACM-the double-Second Division, and the acmk-th largest number Problem Array A and array B have n integers. Array C has A total of n ^ 2 integers, which are A [0] * B [0], A [0] * B [1] ...... A [1] * B [0], A [1] * B [1] ...... A [n-1] * B [n-1] (combination of array A and array B ). Evaluate the K Number in array C.For example, A: 1 2 3, B: 2 3 4. The numbers of C combined by A

Therefore, only I and J are moved, and the complexity is reduced to O (N ^ 2 ). The Code is as follows: 1 int maxsubsum (int * a, int N)2 {3 int max =-infinite;4 int sum = 0;5 For (INT I = 0; I 6

. Here, the original entire problem and every subproblem after decomposition all have the algorithm idea of repeated execution. This is a basic operation, so we can implement it using recursion, in my blog post on the basic principles of recursive thinking to solve problems, I gave some descriptions about recursive thinking. Return to the question stated in our title, and find the largest subsequence and, we can break down the sequence of the

For an array, divide as much as possible into two halves (binary), plus and max consecutive word groups either on the left, or on the right, or across the middle, part on the left, and part to the right.Then only the addition of the left half of the array and the largest continuous sub-array of the same and the maximum number of consecutive sub-arrays to find the right half of the array and the maximum number of contiguous array of the same as the max

Train of thought: if the time complexity requirement is O (n 2 ), the solution is more and better understanding. For example, you can traverse the column at the current I position, calculate the maximum rectangle ending with this I column, and then find the total maximum rectangle.Given n non-negative integers representing the histogram ' s bar height where the width of each bar is 1, find th E area of largest rectangle in the histogram.Above is a his

How to find the second largest number in the array in time complexity O (n)?By setting two variables, one holds the maximum value, one holds the second largest value, and by the process of finding the maximum value, the original maximum is gradually changed to the second largest value. One implementation code is as follows (Java edition):1 /**2 * Find the second

of a function is not the maximum value of a sub-array or a sub-array, but a flag for judging whether the input is valid. If the function returns the maximum values of sub-arrays, what should be returned when a null pointer is input? Returns 0? So how do users of this function distinguish between invalid input and the maximum value of the sub-array is exactly 0? Based on this consideration, I think that the sub-array and the maximum value are put in the parameter list as a reference, and the fun

The stupidest way to do this is to first select the largest number from 16 numbers and then pick the maximum number from the remaining 15 numbers to get the answer, so you need to 15+14=29 the comparison.Since this question requires that the second largest number be found within 20 comparisons, we would like to have a simple method.Assuming that the largest of th

I. Problem Description Input: an integer array with positive and negative values.One or more consecutive integers in the array form a sub-array. Each sub-array has a sum.Returns the maximum value of the sum of all sub-arrays. The time complexity is O (n ). For example: The input array is 1,-2, 3, 10,-4, 7, 2,-5. The largest sub-array is 3, 10,-4, 7, 2, and 18. Ii. Problem Analysis 1. As long as the start position and end position of the

Design ideas:You only need to loop the one-dimensional array around, and find out the sum of the largest sub-arrays.Expand this one-dimensional array by twice times, and after this one-dimensional array, continue to follow the one-dimensional array.Since it is a circle, the length of the array is constant, so only the number of cycles can be limited.Problems that arise:　Limits the number of loops in the process of finding the
