If you decide to change the company's server after considering the comprehensive conditions and requirements, you will be pleasantly surprised if you look at our opinions before purchasing the server. Once you decide which server is the most suitable for your enterprise, it is time to focus on the specific product supply.
You understand what requirements you need to meet with the new physical server, but there is always a gap between what you need and what you can
Say you have an array for whichITh element is the price of a given stock on dayI.
Design an algorithm to find the maximum profit. You may complete at most two transactions.
Note:
You may not engage in multiple transactions at the same time (ie, you must encrypt the stock before you buy again ).
Idea: Use the idea of Dynamic Planning: traverse the array from front to back and from back to back, respectively, find the maximum profits in the range a [0]-

Description:
Say you have an array for whichITh element is the price of a given stock on dayI.
If you were only permitted to complete at most one transaction (ie, buy one and every one share of the stock), design an algorithm to find the maximum profit.
Solution:
You only need to calculate whether the difference between the current value and the previous minimum value is greater than the maximum benefit. The following code is used:

Say you have an array for whichITh element is the price of a given stock on dayI.
If you were only permitted to complete at most one transaction (ie, buy one and every one share of the stock), design an algorithm to find the maximum profit.
The problem is abstracted to find the maximum difference value of the array and satisfy the condition that the values are smaller, larger, and later.
First, I wrote the following code to test whether leetcode has s

This question has two questions, the first question is the longest descending subsequence.For the second ask the number of the longest descending sequence can be solved by asking the first question process. Set Maxcnt[i] to be the number of the longest descending sequence at the end of item I.For all J (1≤j≤i-1) if there is (S[j]>s[i] and maxlength[j]+1>maxlength[i]) then maxcnt[i]=maxcnt[j], otherwise if (maxlength[j]+1= = Maxlength[i]) can take advantage of the addition principle, maxcnt[i]=ma
