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: 1 class Solution {

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

"Topic link"Little Red want to buy some beads to make a string of their favorite beads. The owner of the bead sells a lot of colorful beads, but refuses to sell any strings. So little Red want you to help judge, whether a bead contains all the beads they want? If so, tell her how many extra beads there are, and if not, tell her how many beads are missing.For convenience, we use characters in [0-9], [A-z], [A-z] range to represent colors. For example,

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
