True master only know how to mend!!Record the problem resolution log:When the same or similar problems occur later, it can be quickly found and resolved;To share the logs with the team, not just by one person;Second, the warning is error:Ignore the warning information to continue to develop the code, no doubt the program loaded with a time bomb, it is likely to explode at the worst moment and difficult to solve;　　Some warnings can be a serious mistake!Third, the question conquer:Do not try to un

information? We use max_reach[] arrays, it records the cultimative information in the array. !!!Range computation.2. There is a little pitfall we should take care, that's we only need to reach the last element!

Jump GameGiven an array of non-negative integers, you is initially positioned at the first index of the array.Each element of the array represents your maximum jump length is at that position.Determine if you is able to reach the last index.For example:A = [2,3,1,1,4] , return true .A = [3,2,1,0,4] , return false .Greedy algorithm. Jump forward whenever possible, and if the last position is greater than the length, you can jump out.public class Solution {public boolean canjump (int[] nums) {int

Energy Release Ch round #45-Alan has some traps IIIDescription Alan gets an ore consisting of an energy crystal. for each energy crystal in the ore, if a chemical substance is used to stimulate an energy crystal, it can release energy. The energy release strength is related to the energy value of the crystal and the position of the crystal. Alan made the following definitions to facilitate research. Energy set: a collection of the first energy crystal

BestCoder #45 1003 Dylans loves tree, ProblemQuestion Specify a tree and two operations on the tree. One operation is to change the weight of a node, and the other operation is to calculate the weight of the path between two nodes. If each weight value appears an even number of times, output-1; otherwise, the output has an odd weight (ensure only one) Ideas This is a DFS sequence template question. First, we can obtain the DFS sequence of the tre
