\ r means carriage return, \ n means line break, when we press the return button, the system automatically generates a carriage return and a newline of two characters: A carriage return is only a completion, and the cursor is returned to the beginning. Wrapping is just wrapping, not completing, or putting the cursor at the beginning of the line. Example: (the cursor is represented by I below) 1-- After output abcdef: ABCdef I 2-- After output carriage
Remember to output a carriage return (skip to the beginning of the next line) with 0DH (\ r) and 0AH (\ n) when Windows X86 assembly language. The problem is, under Windows is the first carriage return to change the line or the first line and then enter? Line break on Unix system only \n,mac OS only \ r (said online, no MAC OS, no proof), will not appear above the problem. Now create a new text document th
Preface: Before we analyze the MapReduce, Hive, Redis and Storm, Spark, and other tools to achieve group top n issues, let's look at the Java most original implementation of the top method to lay some foundation for the back, which is why I want to organize into a series. For top n problems, this is achieved in four ways based on the data characteristics, such as merging method, fast scheduling process met

As we all know, given the sample point {xi,i=1,2,3 ...} on the n one-dimensional real space, assuming that the sample point obeys the single peak Gaussian distribution, the parameter expression of the maximum likelihood estimate is: Expectations: Variance: However, have you ever noticed that the variance definition formula we received from childhood is not the same as the maximum likelihood estimate, one denominator is
Question link: http://poj.org/problem? Id = 2828 In a queue, a person wants to jump in the queue, telling you that each new person will be inserted after I and find the final queue. If we use simulation, the time complexity is definitely too high. Think about it. If we reverse the order, the last person's position must be fixed. In this case, we will convert the problem into a reverse scan to show the data, and insert the data after the I individual into the number of spaces that need to be set

This is an answer to zhihu. I personally like this proof. How can we prove that any six points in a plane cannot form a hexagonal structure? If the entire hexagonal point exists, there must be one with the smallest side length.The center will rotate 90 degrees counter-clockwise. Obviously, it is also the whole point. Similar definition ~, They are also the entire point.As you can see, it is a smaller integral hexagonal, with contradictions. This also indicates that the entire triangle d
Given a n-ary Tree, find its maximum depth.The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node.For example, given3-aryTree:We shoshould return its max depth, which is 3.Note: The depth of the tree is at most1000. The total number of nodes is at most5000. S[Leetcode] maximum depth of N-ary Tree n
idea: First search from index=0, each check a bead, response color number +1, if the new color is the total color number +1.When the total number of colors is n, the first continuous sequence that satisfies the condition is found.1> Search from the beginning of the sequence, if the number of colors in the search is not 1, it indicates that the string has other beads have the color, continue to search and update the sequence, starting at index position
