[Training Questions] exam confidence test is the smallest cut, and training exam
Question description:
There are N people in the test room, A and B. If student I is in Test Room A, the total confidence value increases by xi; If student I is in Test Room B, the total confidence value increases by yi. There are also m friends. When I and I are both in the test room, the total confidence value increases ai; if both are in the B test room, the total confi

As the name implies, the "divide and conquer" names themselves have given a powerful algorithm design technology, which can be used to solve various problems. In its simplest form, a divide-and-conquer algorithm divides the problem instances into sub-instances (most of them are divided into two), solves each sub-instance recursively, and then combines the solutions of these sub-instances to get the solution of the original problem instance.Looking for the biggest peeA straightforward algorithm,
Question 1:Suppose a sorted array is rotated on some pivot unknown to you beforehand.(i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2 ).Find the minimum element.Assume no duplicate exists in the array.Question 2: If the array that is allowed on the question has duplicate numbers?Solution: The most stupid method, but also the easiest way to think of is to directly traverse the array, find the minimum value, time complexity O (n), but for the subject obviously will time out. At this point, it is ea
ADD Date 2014-10-15Find Minimum in rotated Sorted ArraySuppose a sorted array is rotated on some pivot unknown to you beforehand.(i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2 ).Find the minimum element.Assume no duplicate exists in the array.This is very simple, because there is no repeating number, the array is essentially ordered, and the method of finding with similar binary complexity O (log n). Code is not a few lines, look directly at code, remember to consider the entire array is not ro

In E-commerce or some ASP applications, the choice of regions is often used.
China has 35 provinces or cities or regions, we choose a provinces and cities, we hope to be able to immediately pop-up corresponding provinces for choice. This feature can be used in JavaScript to
Realize. But China has a very vertical city, and if you use Ja
Title: Enter an integer n, output all the smallest factors of n, also called the element factor.
Where any number greater than 1 can be written as a product of several primes, we call these primes the number factor.
For example:
Input: 120
Output: 2 2 2 3 5
Input: 27
Output: 3 3 3
The Python Solver factor code is as follows:

Priority queue
n rows n digits per row Select a sum sum the smallest n
Suppose only 2 rows
Sort each line first
A1 A2 A3 ... an
B1 b2 b3 ... Bn
Put A1 + B1, A2 + b1, A3 + B1,..., an + B1 into the queue
Then take out a minimum (pop) if it is ax + by then put in a ax+b (y+1) (push) until the n is removed and they are stored in array c
Now there are n so can 22 merge the first and second rows merge the results in the third row and merge ....

Greedy algorithm--n number of connections to get the smallest or largest number of multi-bit integers
has n positive integers that connect them in a row to form one of the largest multi-bit integers. For example: n=3, 3 integers 13,312,343, the maximum number of integers is: 34331213
Also such as: n=4, 4 integer 7,13,4,246 concatenated into the largest integer is 7424613
Input: N
N Number
Output: Number of connections to multiple digits
